my GPU budget is $1100 but i do want to save money if i can. i am using amd right now with the HD 4870 and i want to upgrade.
i will be using CF or SLI so what is better 2x radeon hd 6970s for $760 or 2x GTX 580s for $1000 for FFXIV, just cause 2, crisis, and of course ....... MINECRAFT (lolololol)

which will be better for me. i want to run at max settings w/ 2048 x 1182 res.

If your going straight to dual carding, id buy 2 6950's and overclock them. Fantastic scaling, great overclockers, and only $600 for 2.

Haha everyone else is jealous of your GPU budget! Your current system uses a HD 4870... Do you have case space, power, Mobo and Cooling to run those big cards in Xfire/SLI?

This is the only review of CFX 6970s & 6950s I could find. http://www.legitreviews.com/article/1488/1/

The price differences are enough that it doesn't seem worth it to spend an extra $300+ for the 580s. The only game you mentioned that the review benchmarks is Just Cause 2:

Found a Crysis Warhead SLI/CFX matchup, but all the options perform about the same.
http://www.hardwareheaven.com/reviews/1084/pg17/xfx-radeon-6970-and-radeon-6950-graphics-card-review-crossfire-eyefinity-vs-sli.html

You would save ~$160 (and lose about 10fps in Just Cause 2) by going with the 6950s, but they scale just as well if not better then the 6970s.

what are the other specs of your computer...PSU, CPU, Motherboard. You need a fast CPU to drive 2 of those cards and a solid PSU. Depending on the rest of your system you could save some cash from that 1100 and upgrade other components at the same time.

You think that the HD 4870 is something to sneeze at? Those cards can run stable at 100C and they draw a TON of juice. If he's running a 4870, he'll have no trouble with a 5870. They both have the same power requirements. :sol:

More referring to the original post questioning dual card setups (2 x 5970 or 2 x 580) and whether the rest of the existing system can handle it.

As iam2thecrowe states, we really need to know the systems PSU, Mobo, CPU etc

do you think i should go for 3 in crossfire or wold that be pointless

December 17, 2010 3:05:39 PM

It would be pretty pointless, cards are changing so fast that it's hard to keep up. I got my second HD 4870 because newegg was selling them for $100 after rebate for the XFX (with the double-lifetime guarantee) so I couldn't say no. If either of my cards ever fail, I get it replaced with newer tech. I can't complain about that. Except of course that whatever they send back to me I won't be able to crossfire with my other 4870. :sol: 
December 17, 2010 3:48:05 PM

i think ill go for 2 but i will be using 3 monitors
December 17, 2010 3:55:36 PM

I would go for 3. You'll find that it really helps with your min fps at really high resolutions. (3 monitors, or 2560x) BTW, the 69xx series has amazing scaling.

if you plan to play FFXIV, go get one GTX580 but not 2. ati card wont work well for that game. SLI/CF wont work in window mode. to me, AMD product = lots of bug in many application.

You might want to read the THG article comparing the scaling performance of SLI vs. Crossfire

http://www.tomshardware.com/reviews/crossfire-sli-scali...

Based that review, I would be inclined to go with nVidia cards for resolutions over 1920x1080. Regretably I have no personal experience with the larger monitor.
December 17, 2010 4:40:18 PM

that would be great, if the article wasn't outdated. But there aren't any 6xxx cards in there... Those are the ones that scale really well.

If you are interested in a dual card setup, and your budget is $1100, the ONLY way to go is dual GTX580's. There is nothing that can beat that setup, except three in tri-SLI.

In general, the GTX580 is the top single GPU right now. It offers the following advantages:
-Top performance
-PhysX
-Better drivers
-Better DirectX 11 tesselation performance
-It is one of the quietest video cards
-Better scaling and stability in SLI (vs. Crossfire setups. SLI is more Plug and Play, while Crossfire requires the user to download profiles for new games.)
-Better scaling for overclocking (the ratio of performance gained per clock cycle increase) with minimal impact on noise and temperatures.
-In SLI, the GTX580 is quieter and cooler than the 6900 series in Crossfire.

As an example, I fired up Battlefield Bad Company 2 last night on my GTX580 with 32xCSAA and 16xAA @ 1920x1080, all details turned up to maximum. There wasn't even a hint of strain on the graphics card, even during intense firefights, everything was smooth and the graphics were great. Not many single cards can do that.

wow it looks like i will get either 2x 580 or 3x 6970s but i cant chose...
i will be playing at 6144 x 1182 res
will i have 6 GB of vram with 3 2GB cards or just 2GB and isn't 1.5GB in the 580 a little low for 6144 x 1182 resolution.

what do phisX and CUDA really offer. i will be using photoshop cs5

6950 crossfire is beasts ;)  its a good way to go but remember that nvidia has the upper hand in tesselation.

Why would you buy a 580 for any reason right now? Its pitiful value! The 6950, 570, and 6970 are the only high end cards to buy IMO. Seeing as how the 69xx series has fantastic scaling, it would make sense to get 2x 6970. Since you can OC a 6950 for the same performance as a 6970, its even more logical to get 2x 6950.
December 17, 2010 6:16:24 PM

what about cuda and phisx though... my cpu budget is pretty large sooo......
December 17, 2010 6:20:39 PM

im leaning towards 3x radeon 6970s

That setup will be much louder than you realize and much hotter than you would want. The GTX570's, when paired in multiple GPU setups show barely any increase in noise or temperatures.

"As we have seen in the past the sales of a product can be hampered by a cooler which produces high noise levels. For the 6900 Series this isn't an issue in single card mode as the videos below show. The same cannot be said of the CrossFire testing though. As well as seeing temperatures up to 100c when we placed three cards side by side on our Gigabyte motherboard the noise levels being produced in dual and triple card mode were, to be honest, unbearable."

Sounds like your mind's made up, especially if the word "unbearable" doesn't change your opinion.

If you are curious what you will be missing in terms of PhysX, I suggest googling it to see for yourself. Most opinions you read here will be hopelessly biased. Those who have it (Nvidia) really like it, those who don't (AMD) don't like it.

I have to agree,1 6950 is good enough for any game that is out at the moment,so with two in CF and clock them to the same as a 6970 you are good for the next couple of years. IMHO i would not go three way CF,it would be a waste of money tbh,if one 6870 can run upto 4 30" tv`s then 2 6950 is going to be all the horse power you need.

+1 to matto17secs comments in this thread so far. If the things listed above don't matter to you then by all means CF a couple of 6970's. On the sort of $ you're talking, although not the best value, 2 x gtx580's is my choice.

While Photoshop CS5 does not support any native CUDA-accelerated functions, CUDA does accelerate specific Photoshop CS5 plugins as you can see in this THG article: http://www.tomshardware.com/reviews/adobe-cs5-cuda-64-bit,2770-8.html
If you use certain plugins for Photoshop a lot you may want to pick a Nvidia card.

Physx is a proprietary physics engine used in some games. Since Nvidia revamped their website its hard to find the complete list of games supported, but you can see some of the modern ones at geforce.com. Click on the Physx tab on the right side to see the current games & demos that use it: http://www.geforce.com/#/GamesandApps
Some listed here too:
http://en.wikipedia.org/wiki/PhysX#Title_support
FFXIV, Just Cause 2, & Crysis do not use Physx. Some popular games that use Physx are Metro 2033, UT3, Mafia II, Batman Arkham Asylum, & Mirror's Edge. If the game does not use Physx, it is an unused feature.

There are several physics engines used in games that run solely on the CPU rather than on the GPU that many developers use such as Havok & Bullet. The advantage to Physx is that it uses the parallel processing capability of a GPU to perform many calculations simultaneously, although now multi-core CPUs are more able to do the same thing.

i will go for the 2x 6970
December 18, 2010 3:58:14 AM

just looked and 3x 6970s with 3x monitors is about $150 ovr my $3200 limit w/ the rest of my system added
December 18, 2010 4:12:32 AM

Getting 3 monitors and 2 gpus then?
December 18, 2010 4:50:52 AM

sweet, that will be awesome..
December 18, 2010 5:40:27 AM

but should i go for the 580s or 6970s w/ such a high res
December 18, 2010 5:41:27 AM

i think i would need at least 2GB of vram in this case but 1.5 might be suitable
December 18, 2010 5:48:57 AM

1.5 should be fine, my 580s run it fine at 5760*1200, soon to be 7680*1600
December 18, 2010 5:53:12 AM

i don't game much, maybe 1-5 hours a week... usually about 1, but on the week of a new week i may game for 5. when i do play i prefer the top quality... and doesn't a 980X seem a little over priced since not many apps will use 6 cores and when they do there will be a cheaper alternative with about the same performance. my budget is usually high but i tend to lean towards the price/performance on the CPU. i know it is the best cpu out, other than some $5,000 xeons for servers, but i cant bring myself to justify buying it. no pun intended, i wasn't trying to insult anyones buying decisions.

i might just forget about building a system today and wait until mid 2011; by than i might decide to raise my budget to $4000, opening a lot of new options.
December 18, 2010 6:34:11 AM

Lol, there's always going to be more coming out. As for 980x, it really is poor price/performance ratio, only if you want the absolute fastest.

AMDs 6990 will be out by then. On that sort of budget could be the card for you :p 
December 18, 2010 9:14:46 AM

you want to save money but still want to have sli or cf?? why not considering gtx 570 sli?? 2 gtx 570 only costs $700.... you save 300 while still maintaining good performance...
December 18, 2010 9:20:04 AM

however a gtx 595 will also make its appearance at time,and then we will see hd 6990 vs gtx 595,and gtx 595 will beat it,however right now gtx 580 is great investment for next 4 years.

But a terrible value...Does anybody realize going from the 6970 to the 580 your paying 40% more for 10% more performance and worse scaling? Even from the 570, thats 45% more for like 15% better performance. Thats pathetic value. No reason to get it.
