Crossfire or SLI

which one is better

crossfire since the mobos are not nvidia chipsetsmodai119

So all those nvidia northbridge chipsets are imaginary products??

like my evga board with a nforce e-7150?? I guess I am imagining things in my case.

soo.... what do I need to run CF??

Crossfire is better...however what everyone is failing to mention is, its only better if you have one of the new X38 chipset boards, so you can run each card at full 16x PCI-E bandwidth.

otherwise, SLI does outperform Crossfire in most real-world apps. benching, Crossfire does seem to do better. and im speaking from experience by the way

crossfire ftw

good mobos to get for CF

AMD: 580x chipset (ASUS, K9 platinum), 790fx (supports up to 4 ati cards via crossfire)

Intel: im not to sure on intel but i have heard good things about the x38 motherboard

soo... what mobo do you need to run CF??

well can you point me out to good mobo..??

like this one or that one?

I am planning on running Q6600, DDR2 SDRAM DDR2 1066 PC2 8500.

stuff like that...

i remember when everyone was busting ATIs chops bout their crossfire. Now its the best multi-GPU platform9mmSpliff

get an SLi' ready mobo and then CF on this board with no problems. so basically ALL SLI ready motherboards also support Crossfire too.yoyo462001

What?

btw is there any kind of benchmark results CROSSFIRE vs SLI??

some pics or something?

CF all the way!!!!

?huh...i thought you needed a CF Mobo to supprt CF....since when did cf run on a sli mobo

Crossfire doesn't work on a SLI supported board. I'm currently running X1900XT and a X1950 CF edition card in crossfire and enjoying it every minute of it.

CrossFire enjoys one additional rendering mode over SLi, but it only works in Direct3D games. If you've any OpenGL games that do not have a game profile in the driver readily available, you're SOL because the driver will disable CrossFire altogether and ATi's driver provides no way of creating your own profile or forcing it to be enabled. Seems even after all these years, ATi still has a deep hatred for OpenGL. :| Unless you get an HD 2*** or later CrossFire, you'll almost have to remember to get yourself a (super rare and super expensive) CrossFire Master Card which would use a proprietary dongle to link the two cards together. SLi works comfortably with OpenGL and DirectX and if your app or game do not have a profile readily available, you can create one! :o SLI has been around longer, so you're also likely to find better, more compatible game profiles so that the whole "oh you only get 30% improvement" myth is debunked. Further, each new generation of GPU's seems to get an increasingly larger performance difference when linking two of them together in SLi too. That may be from better optimizations in hardware, drivers, or a combination of them, but it's something worth noting.codezer0

lol now Louie...u know your only making a stupid statement like that coz your an AMD/ATI user. very close minded statement. i have had Crossfire and SLI setups, currently SLI. Crossfire has only just started to outperform SLI on Intel setups, with the introduction of the X38 chip, allowing dual 16x PCI-E slots. plus ATI are finally moving along with drivers.

in gaming and real world apps, SLI has always done better in the past. a lot more games support SLI over Crossfire since Nvidia have more money and can pay them to make it that way. for a game to really utilise multi-gpu, the game needs a specific profile. a lot more games have SLI profiles than Crossfire. the devs are finally escaping this whole now and creating simple multi-gpu profiles. specific profiles will always perform better though, but you lose compatability.

the two are very close, it really comes down to which motherboard/CPU you prefer. if your into AMD, go Crossfire straight out. if your into Intel, well the choice is yours. both perform pretty much equally well now in real world apps. Crossfire seems to outbench SLI, but only at extreme clock settings. im guessing thats due to the massive cores on the latest ATI cards causing some pretty heavy bottlenecking.

but saying one is complete **** compared to the other is a poor fanboy statement, nothing more. both multi-gpu setups lack support, compatability and funtionality and are really just for people with money burning a hole in their wallets and perhaps a strong interest in benchmarking. if you had to go with one or the other, just choose your favourite vid card manufacturer/brand and stick to it. new drivers and support are coming out all the time, along with new products. you can never stay ahead of the market, so just take a seat and enjoy the ride.

iirc any ati card 1k series and up don't require the master card for CF.achilles614

[QUOTE="achilles614"]iirc any ati card 1k series and up don't require the master card for CF.codezer0

Actually, all of the 1K series could do crossfire without the CF edition card except for the X1800 and X1900 series.

I thought so as well until I had to do some research to see if my setup would work correctly before I ordered it. I could be wrong but almost all sources pointed that those two series of cards were the only ones to require the CF edition card. However, the X1950 didn't require a CF card but it had one anyways. (Trust me, I'm currently using one)

CrossFire scales better than SLi, assuming you have either X38 based motherboard or 790FX based motherboard:
http://au.gamespot.com/pages/unions/forums/show_msgs.php?topic_id=26065702&union_id=11552

SLi:

CrossFire:

If you're truly intent on going multi-GPU, go for CrossFire. AMD may not have a halo product now, but they will do soon (HD3870 X2) and it should cause some trouble to NVIDIA once its put into CrossFire.

As for motherboards:

Intel CrossFire: ASUS P5E (X38 Chipset--don't get fooled by P35 parts) or Gigabyte GA-X38-DQ6
Intel SLi: None recommended by me. NVIDIA nForce 680i mobo's (as with 975X/P965 mobos) has still yet to support Intel's QX9650 Yorkfield (Penryn family). Wait for NVIDIA to release the 780i for SLi support and Penryn support.

AMD CrossFire: Gigabyte GA-790FX-DS5 (only two way CrossFire, but HD3870 X2 only supports dual CrossFire, as it already has two RV670 GPU's on board), DFI's upcoming 790FX mobo or ASUS' 790FX upcoming mobo.
AMD SLi: Look for any NVIDIA nForce 590 SLi mobo or wait for the 780a SLi mobos.

Be warned that Phenom is slower than both Core 2 and Penryn Core 2, clock for clock, so you may run into CPU bottlenecks going with Phenom.

What is an X1900XT + X1900XT CF equal to in terms of later gen cards?
If its 80% increase then that should be quite high end. I'm thinking of getting anothe X19xx series master card to CF as it would be cheaper than a new GFX card.

It can't run DX10 becuase its a DX9 card...of course it doesn't have a chance it won't even run them period.
