Dual 5850s. Same price as the gtx480, but much better.

GTX 480 is faster then the 5870, then the GTX 470 is faster then the 5850. And in some cases the GRX 470 nearly matchs the 5870. So its up to you with what you want. The GTX 400's would be abit more future proofing then 5000's.

Um no, average price of 5850's are $310-320, then the GTX 480 are going to start at $500, so $620 vs $500 while producing more heat and using more power with two 5850's. And then you can SLI 470's for $350 a peice and still be alot faster yet.

Also take a look at SMC's blog TC. Many reasons to get a 5870 over a gtx 480. SMC knows what he is talking about 99% of the time.

Again I proved you wrong dual 5850 arent cheaper, and every benchmark done shows that overall the GTX 400's are faster then their ATI counterparts. Plus its been proven that ATI's 5000's dont handle tessellation to well and takes a big hit in performance.

You're seriously way too pro-Nvidia lately when it comes to Fermi vs. Evergreen. It seems like 3 out of every 4 reviews I read of the GTX 470/480 says the same basic thing.. "While slightly faster than the 5870 and 5850, we can't recommend the GTX 470/480 due to the price difference, along with the high power draw and heat consumption." I don't understand how you keep recommending the Fermi cards when they're generally being regarded as a disappointment.

Oh, if you want a CrossfireX setup to compare to the GTX480, look at getting 2 5830's.

So let me get this straight.. You're recommending the GTX 480 over the 5870 for performance reasons despite the fact that it costs more, uses way more power, and produces way more heat.. Yet you're using the price card to argue against him getting 2 5850's while admitting that they will use less power and produce less heat than a single gtx 480? What exactly are your priorities?

When people ask what they should go for Nvidia 470/480 or AT 5850/5870, and they say I want the fastest one under $600 you you say ATI 5870 your lying to them plain and simple. Not everyone cares about the power load or the extra heat. And some people like the Nvidia features bettter then what ATI offer too. And Im getting tired of the ATI pro movenment saying Nvidia = fail because they have the fastest single gpu card but having a bigger power draw and produces the same amount of heat as a dual gpu. Granted the heat isnt a pro , its a con but some people just dont care. Plus we dont know what mature drivers can do for the GTX 470/480, like what the 10.3 did for ATI's. The last Nvidia driver boost alot of cards performance in most games.

The TC didn't say he wanted the fastest one for under $600. Nor did he say he wanted to fastest one at all! Where are you getting this from?

Some Nvidia fanboys LOL. Nvidia does not equal fail, but if they don't make some improvements in their refresh series then they will. What pro ATI movement? It just seems like you are getting mad because alot of people went with ATI this round and think we are all pro AMD. Nvidia's cards should be much better than they are.

You're not making much sense, that's why it's coming from all over. First you argued pure performance and heat/power issues over a price advantage, then you argued a price advantage AND higher power use/heat over higher performance.. Then you made up some imaginary requirement that the TC didn't even post. I'm not sure where you're coming from on this one.

No, no, no, your not understanding, just about every GTX 400 vs ATI 5000, to people just asking whats faster/betterthread the ATI fanboys pull out the power/heat card and dont even acknowledge that they are faster and have a few more options. And comments like what miller said that dual 5850's are cheaper....... and then dont account for the power/heat draw from two 5850's too, being hypocritical in that respect.

I second that. I'm waiting for a die shrink / new revision from nVidia. Maybe Christmas, but likely early next year. There should be some decent DX11 games out by then...

Bro, I would stay away from a gtx 480. The heat that thing makes is crazy. I use to think "oh who cares how hot a crad is. What does it matter." Let me tell you dude I will never buy a card again until looking at the heat it makes. I just purchased two 5970's and those things idled at like 60c. Load was 100c!! The fans would be blowing at insane speeds. Things were flying off my desk lol. The noise was so annoying. Stick your hands by the heat being blown out too long and you can burn yourself. That is how damn hot these cards can get.

Its almost summer time and I am telling you no freakin way I am having those cards in my set up during the summer. I took mine back and I put back my 5870. Wanna know the temps of my 5870? Idle 41c and 80c load. Whisper quit too... I am telling you... you do not want a hot set up. I would get a 5870

GTX 480 is better than HD 5870, but HD 5970 can beat GTX 480 (higher fps in many games).

What case & psu do you have? because ethier one can play a big role in why your temps are so high.

The only thing I beleive the gtx 480 has over the ATI cards is the multi gpu scaling.... Nvdidias SLI is much much better than Crossfire. Period! But here is the catch. Good freakin luck running more than 1 gtx 480. I head Nvidia even sayng if your gonna run 2 gtx 480's to have one pcie slot in between them.... I wonder if it is even possible to run 3 in SLI lol. Your case would melt...

No, I do understand. On one side you argue that they should get the GTX 480 over the 5870 because of pure performance, despite the disadvantages of price, heat, and power consumption. Then when somebody comes back with an ATI solution (2 x 5850's in crossfire) that will beat the GTX 480 on pure performance, you point to the price and higher power draw as a big deal. So what IS the biggest deal here?

shoul i get a GTX480,HD 5870 or dual 5850s?dylanzzz
2. He's Australian so (2) 5850s (@ $369 each) WOULD be cheaper than a gtx 480 (@ $749).
3. They DO NOT produce more heat than a gtx 480:[spoiler] . [/spoiler] 4. They DO NOT consume more power than a gtx 480:[spoiler] . [/spoiler] 4.

Lol, your chart even shows it uses more power and the combined heat output will be more then a single GTX 480. Any ways getting dual 5850's would be a waste. I would just get a 5870, or GTX 470/480 depending on what you want in features. If you like Physx or do alot of rendering/encoding CUDA from Nvidia speeds everything up. Or ATI if you worry about heat/power if your psu or case cant handle the load,

You should read the chart again XD It looks like you're taking the single 5850 temps and power load and just multiplying it by 2. There's a crossfire reading right there. :P

Look, wattage and heat are directly connected. And a 5850 can use upto 188w and you do have to double the wattage ifyou have two. 188+188= 376w. And all tests with the GTX 480 draws less then 370w by itself. So which means that the heat that is produced by two 5850's will be more then a single GTX 480.

Are you on something?; the Hexus charts DO NOT show that.

What are you talking about? 5850s can use upto 150w and 2 of them would STILL be less than (1) 480 (@320w):[spoiler] . [/spoiler] This chart is showing the Hexus one to be accurate because of the ~20w difference. I showed you 1 review where (2) 5850s stayed below 90 Celcius. Can you show me the opposite?

EDIT: btw, where would be the limit in your wattage/heat for you? Is it at 375w? Is it based on performance?

lol my card is such a beast :) 168W usage!! but there is something called future proof. like i got my gtx 260 1 year ago, i also saved 75% on the card, but my card will last me another FOR SURE 2 years becuase games wont get that fast. see hence the 2 years (in English that means future :o) i also suggest nvidia not because it is better than a single ATI 5000 but becuase of Cuda and Physix, trust me u wont want to miss that.

Coming from a guy that thinks there is such thing as future proofing in the PC world. HA! TC either dual 5850s or a 5870. This other guy is way too pro Nvidia.

O yeah Im so Nvidia that I recomend ATI cards to people all the time :roll:. Again I proved you wrong dual 5850 arent cheaper, and every benchmark done shows that overall the GTX 400's are faster then their ATI counterparts. Plus its been proven that ATI's 5000's dont handle tessellation to well and takes a big hit in performance.

GTX 480 doesnot use more then 300w pci-e slotlimit, its between 250w-270w, And again im not talking about how hot the gpu gets im talking about heat output . A 125w cpu canproduce 125w's of heat while using upto 125 watts of power off the 12v rail while needing 7.5 amps at full use. You have two gpu's producing 150 ish watts of heat (my bad on the 188w thats the 5870). Even still dual 5850's produce more then 300w of heat does not not matter how well the cooler cools the gpu/ram that amount of heat is still being dumped into the air.

To 04dcarraher: do you have a chart with the power draw of the 480 and 5850 (just the cards, not the system)? I'd like to see it. And are you gonna answer the question of where you put the limit?

EDIT: Misunderstood your earlier statement. Fixed.

[QUOTE="04dcarraher"]GTX 480 doesnot use more then 300w pci-e limit its between 250w-270w, And again im not talking about how hot the gpu gets im talking about heat output . A 125w cpu canproduce 125w's of heat while using upto 125 watts of power off the 12v rail while needing 7.5 amps at full use. You have two gpu's producing 150 ish watts of heat (my bad on the 188w thats the 5870). Even still dual 5850's produce more then 300w of heatdoesnot notmatter how well the cooler cools the gpu/ram that amount of heat is still being dumped into the air.smc91352
Dude; you said it yourself that it uses more than 300w right here:
And all tests with the GTX 480 draws less then 370w by itself.04dcarraher
Again, do you have a chart with the power draw of the 480 and 5850 (just the cards, not the system)? I'd like to see it. And are you gonna answer the question of where you put the limit?

that was a typo "370w" :P I meant *270w*

I see. I edited my post because you said "less than" but didn't say how much.

But yeah, Techpowerup said it CAN use more than 300w while running Furmark. I wanna see your chart, please. :)

All you need to do is take the average of total system power consumption and subtract the difference between the 5870 and GTX 480, Nvidia has rated it to a 250w max, but the math says close to 270w. Also a gpu cant use more then 300w with pci-e slot, 8pin and a 6pin 75w+180w+75w = 300w limit. The 5970 had to be downvolted to be below the 300w limit and its at 296w onfull load.

Ok, the 5870at max uses188w so 311-188= 123w for the system alone.

So you take 389-123 = 266w for the GTX 480

all I know is I have a single 5770 and it runs my games all high settings no problems. I dont see the point in buying these new hugely expensive cards. I suppose the future proof argument will come up here.

Sure, and no pressure; but so far that's 3 to 0. (Hexus, Techpowerup, PC Perspective) PC perspective 5850 = 292w. Add 150w for a second card and that's 442w. They put a 480 @ 448w. That's 6w more:[spoiler] . [/spoiler]

okkie so what i dont understand is how did this go from helping this poor fellow choose a card, to a all out war with Nvidia vs ATI. Nvidia is a smarter choice becuase u get all this great features and ATI gives u, umm a cooler pc :S. doesn't seem to me that u have an argument smc.

You wonder how? Nvidia fanboys started this one. By saying stuff like you say. SMC does not have an argument because the info he is providing is 100% true and 04dcarraher won't admit to it. At least Nvidia fanboys stay consistent.

I already gave the reasons to get the (2) 5850s. He contested 2 of my points and we're trying to see if we can come up with a conclusion. The "great features" thing is not a point as objective as the performance gains. (not to say they're worthless though)

Ok, below shows the dual 5850 with system using 478w, so minus 302w = 176w avg for the system under load.

There below shows every single card using under 300w including GTX 295 and 5970. The GTX 480 cant use more then 300w because of the single pci-e limit of 300w. Pci-e slot can only usemax of 75w, 6 pin =75w and the 8 pin = 150w max of 300w. Why do you think that ATI had to underpower the 5970 to make it below the 300w pci-e limit?

id rather wait for nvidia to revision this card before even purchasing it yest its a powerful card but its not worth the money at least me it's not so i'm buying my 5870 in two weeks :)

If you weren't gonna show the 480's power draw why did you even bother with the math? :| You keep saying that but I could show you benches were you add 150w to a 5850 (making it 300w in gpu power draw) and the 480 would still come out to more.

-Anandtech:[spoiler] .
307w + 150w = 457w.
gtx 480's 479w > 457w
therefore gtx 480 > 300w [/spoiler] -HardOCP:[spoiler] .
316w + 150w = 466w.
gtx 480's 480w > 466w
therefore gtx 480 > 300w [/spoiler] -LegitReviews:[spoiler] .
324w + 150w = 474w.

300w is the available power you can put to a single lane. Right now, the beefiest cards you can get use PCI-E and 6-pin + 8-pin power connectors. Each rail can only deliver a certain about of voltage and amps, so if you add all the power up: PCI-E = 75W 6-pin = 75W 8-pin = 150W Total = 300W ... Max The GTX 480 and 5970 cards use 6pin+8pin connectors, so can only pull 300Wmax . But since the 5970 has a much larger heat sink, it can handle all the power it pulls in. engineers are making the new PCI-E 3.0 standard to increase the rail wattage above 75W, so an extra 6 pin 75w or 8-pin 150w connector is no longer required. Rumor is they're testing up to 300W... from just the PCI-E lane. But since the cooling problem still exists with all the heat, any cards over 300W will have to take up 3 lanes. This brings up problems with just supporting the weight of over a kg of PCB and metal fin cooling. the electrical limit, as well as the cooling limit of a double wide air-cooled card on a PCI-E lane.

ok then...if the 480 is under 300w so are the (2) 5850s...the whole 300w means nothing because the 480s STILL use more power.

are u crazy, great features includes drivers to, fyi nividia drivers lately having been giving amazing performance boosts to games, not only the cuda and physx thing. remember software is just as important as hardware. look at ati 3000 series, their hardware was amazing but their software brought down performance becuase the drivers wont good

so u see my point? well then thats nvidia 1 ati 0 :) BTW 5850 covers 2 lanes. so that means the limit raises, from 300 to 600W becuase 2 times 300 is 600. just alittle tip :D

Which means that the GTX 480 cant use more then 300w the 5850's can since each card can use 151w :P so its 302w , Nvidia rates the 480 to be 250w and 470 as 215w. I believe that the GTX 480 is under 290w and 470 under 280w for sure. Ethier way the GTX 480 has to use less then 301w to make the single pci-e slot power limt requirement.
