Anyone have HD5770's crossfire?

I thinking about picking up the dashing couple in April and I was wondering how it performed in your system, with these games;

Mass Effect 2

Crysis/ Crysis WarHEAD (Has to be constant 60 FPS no drops) Gamer/High Preset for everything and ethusiast water

Dirt

Or should I just wait for benchies of the GTX 470 (I can only get one of these my PSU only allows 6+2x2 connectors)

I am totally indecisive about my GPU decisions as spending $350+ at one time is alot since I am young.

Current Resolution: 1440 * 900 looking at 1680 * 1050

Current GPU: HD 4850

Current CPU: AMD Phenom II X4 920 ~2.8 GHz

If you're going for some serious gaming, I wouldn't put two HD 5770s in CrossfireX. If you want to crank up the filtering and shading effects you need fast memory. Unfortunately the HD 5770 is crippled in this department, as it only has a 128-bit GDDR5 interface. My dad has an HD 5770, which works for him because he isn't too serious about his gaming. When playing Mass Effect on his HD 5770 it performed fine until I turned on 4x AA and the framerate cut in half, something a single HD 4870 can do no problem (the HD 5770 and HD 4870 are the same on paper, only HD 5770 has faster clocks, DX11, BUT 128-bit memory. HD 4870 has 256-bit memory).

My advice to you, pick a card that has the most power on a single chip, not split over two. HD 5870. Packs the same amount of power of two HD 5770s on a single chip, so you don't have to worry about CrossfireX scaling, also has a 256-bit wide bus. It'll easily be better and in the same ballpark price range. Plus, later down the line if you feel you need more, they'll be cheaper and you can add another.

For higher resolution with lots of filtering, it's hard to pass up the HD 5870.

I recommend the HD5850.It is on your budget, only 300usd, it is the best budget/performace ratio out there.

If you have the cash the hd5870 is 400USD and amazing, Too expensive tho, since is the single chio KING atm.

I wouldn't buy a 5700 series, because will become dated very quickly when real dx11 games starts coming, if you are going for dx11 go all for it, CROSSFIRE should only be used when you want to upgrade, you never should buy 2 cards together to crossfire at the start. Doesn't make sense specially when there is a higher end single chip avaible for the same price.

I don't think is worth waiting for nvidia. I miself think nvidia won't be worth until their second generation dx11 cards and devs start using CUDA C++.

I see their flagship dx11(470gtx/480gtx) as too experimental for my taste. I will let the enthusiasts pay the price for the technology advancement... will buy the simpler and cheaper version the comes later. Just like the G80 users payed the price for us to have the 8800gt G92 few years ago.

So, I think I am going to have to upgrade my PSU :(

700 watts all for nothing...This is what i was trying to avoid, current PSU can only handle 6+2 x 2

So I would be able to only get only one GPU and never have the ability to Xfire :|

Any of you guys in the market for a PSU (never get this one)

Alright so 5850 it is, but will it do all the things I mentioned above?

Please show me where this problem of severe drop in FPS happens using these reviews...

http://www.pcper.com/article.php?aid=882&type=expert&pid=6

http://www.overclockersclub.com/reviews/powercolor_pcs_5770/7.htm

(I choose em cause they have more recent drivers)

I would LOVE to know where you guys get this 4870 > 5770 BECAUSE of a 256bit memory interface because I haven't seen a game 4870 > 5770 by an significant amount that would validate this claim. There is no resolution a 4870 can play that a 5770 can't so that basically throws htat theory out the window. Seriously tired of this.

5770 is great at 1680 x 1050 or below, 5850 for higher and 5870 for very high resolutions. Crossfire 5770's perform up there with 5870 sometimes beating it sometimes not. But I haven't seen benchmarks with recent drivers for 5770 crossfire so it coudl be better than that now.Human-after-all

tbh i think itd be betetr to place the 5830 for higher and 5850 for highest resolutions the 5870 is greater preformance at the highest resolution but really isnt AS necissary as you consider it to be.

That's exactly the cases I said the HD 4870 was better, under heavy framebuffer situations. That would be gaming with high resolutions with lots of filtering. When I noticed decreased performance in ME1 it was at 1920x1080 with 4x AA and 16x AF. Under the same specs with a single HD 4870 512MB performance did not degrade as much as the HD 5770 1024MB (which was overclocked to 950 core and as far as I could take the memory).

The core on the HD 5770 is better no doubt, but it does lack some framebuffer performance compared to the HD 4870. My statements aren't false, in fact I stated that it would be worse at high resolutions with lots of filtering. Other than that HD 5770 is a great card. Also getting the same performance on a single chip is good advice as well, the prices aren't too far off

I would get you number values to show the ME1 performance, but I don't have access to that computer anymore as I just moved back on campus.

Don't just listen to what some people spew about "128 bit memory" without even showing any statistics or proof to back up their claims. I have two 5770, they perform very nicely with 128 bit memory..

They're equal to 5850 in Crysis.

They beat 5850 in 90% of games.

Equal or better to 5870 in most games.

Equal to crossfire 5850 and 5870 in some games such as FO3.

http://www.guru3d.com/article/radeon-hd-5770-review-test/20

Surpass 5870 and even 295 gtx in some games such as MW2.

They beat 5850 99% of the time.

No reason not to get a pair to be honest.

CrossfireX is a different story. Single card is similar or better than HD 4870 except in high frame buffer situations. CrossfireX on HD 5770s seems like a very good combination. It's not spew about "128-bit". I've said under very specific circumstances performance is worse.

This is what I'm talking about. At lower res, HD 5770 is faster, as resolution and filtering are increased, HD 4870 gains the lead. I don't know if my particular experience just seemed really bad with Mass Effect 1. I seemed to get the same experience with Supreme Commander. Nonetheless it left me a bad aftertaste of the card. Overall the HD 5770 and HD 4870 are pretty much neck and neck. Unfortunately these reviews don't have a 1GB HD 4870 which performs better than the 512MB flavor. I'm just stressing it because it's something I experienced. It might have been biased to the Unreal 3 engine. TechPowerUp! did a UT3 bench, but they never used AA.

EDIT: I guess a better comparison is the HD 4890 vs the HD 5770. The core clocks are the same (850MHz), the difference in memory is 128-bit vs 256-bit. The HD 4890 is better. Because the HD 4870 is pretty much the same as the HD 4890 with a slower clock, the HD 5770 becomes the case of whether or not the faster core can make up the difference in framebuffer performance.

one 5770 is a joke enough, now you want two of them at the same time? this is like laughing twice to the same joke.GazaAli

Well if crossfire 5770 is a joke. Then that means 5870 is a joke.

really you must look at the facts and the benchmarks before you post.I can go and post benchmark from every site which has benchmarked crossfire 5770 and prove xfire 5770 is no joke.

And what can you do? nothing but run your mouth off and troll. becuase you ZERO facts to back up your claim. GG

so the 5770 does not perform very well in DX11 but is a good card in that it can max non-DX11 games? so why exactly people pay more for the 5770? why not just get a 4870 for less :roll: 5770=throwing money and 2x5770= a joke.GazaAli

Go CF your 4850 and be done with. If your going to CF you would do stuff that puts the memory bandwidth to the test as in max AA/AF something that 5770 falls short on with 128bit, I assume a very awesome oc'er though if your into that. Since you have that kind of money I say 5850 is a very nice card to have and a much better purchase than cfing 5770.

Well you can always mixed the brands, heck go get a 4870 and cf with that itll just downclock itself to 4850, or the almighty 5850.

Actually, it does help in Crysis quite a bit when the game is patched ane when you use later drivers. Take a look at this article. The twin 4850 512mb's were able to handle Crysis on very high settings at 1080P while pulling off 37FPS average. While introducing AA brings the system to it's knees at higher resolutions, I still consider that result very impressive, especially since it's faster than a single 4890.

Oh, and to respond to your other post, you can mix two different 4850 brands and they'll still run perfectly in CF.

That's the reason why I've got a case that lacks a side panel. For me, as long as it runs, it runs; I hardly care what the PCB or cooler looks like ;)

To get back on topic, your decision is probably the best if you're looking towards future games. The 512MB VRAM on your 4850 is starting to show it's limits nowadays, especially at higher resolutions or if AA is introduced.

Why would anyone want to mix a 4850 and a 4870. Bad advice imo. As that one 4870 which is going to be downclocked to a 4850 in that xfire setup, would be almost as strong by just running it by itself instead of xfire. And you would have less power usage and less heat..

To run Crysis at 60fps minimum you need a serious card like 5970.

If you want a good crossfire setup for todays games, and the next year or so - 5770 is good. I know I plan to use 2x 5770 for a good year and a half and then I will upgrade. And that is what I always had in mind when I bought these cards.

If you're looking for a GPU that you want to keep for a good while (ie 2+ years) 5870/5970/GTX 470/480. is all you want to be looking at really.
