Hey,

Im running a AMD FX 8350 with 16gb 2133 CL9 (Quad channel) ram.

I BOUGHT 2X MSI TWIN FROZER II GTX 580

I BOUGHT 2X RADEON 6990 HD

(I got good deals on all gpu's)

WHICH GPU'S SHOULD I RUN!!!!! IM SELLING ONE SETUP AND USING ONE!!

From what i've seen, the single gpu benchmarks, the 6990 kills it. But with DUAL cards, the 580's make a come back! But I just dont know what to believe and what to do!!!!

P.S. I'm using this setup for both WORK and PLAY! so computing power in video rendering and image editing is a big priority.

Please help me guys, im torn on this decision!!

Thank You!


*WILL BE OVERCLOCKING THE SETUP I CHOOSE IN THE FUTURE

that RAM is running Dual Channel on that chipset.

No reason to buy old technology (6990/580's)


2x 6990's would wreck 2 580's as 2x 6990's is essentially QuadFire 6970's

but i doubt your Processor can handle 2x6990's.

i would use ONE 6990 versus 2x 580's as 2x 580's would put out more heat (SLI GAP) and take up more room in the case.

I also have that case, and both cards are going to require you to remove the Harddrive Bay

The harddrive bay removal is all fine. What do you mean no reason to buy old technology (6990/580's)? I've picked up a liquid cooler for my cpu, overclocking it to 4.8ghz or 5ghz if possible, and I think it should handle the dual setup fine no?

You could just try both setups, and see which one yields the most fps.

Is your processor overclocked? you could try to overclock it to around 4.4-4.5 and see what happens, you are extremely lucky to have 2x 6990's for cheap, it would almost be a sin to throw that away thumb.gif

EDIT: i read that you picked up a liquid cooler, if you can get it to 4.8+ my guess would be that you would be able to run 2x 6990's great.

Thanks, my buddy has more. Sell you them for $350 a pop. Thanks!

2 6990's and then use one 580 as a Phys X card drool.gif

if you can get the overclock to 5, id use two 6990's.

In terms of raw performance running two 6990 in quadfire will eat gtx 580 SLI for breakfast but quad fire scaling is not always that great so there are plenty of cases where two 6990 aren't going to be much faster then 580 SLI though there are also lots of times when quadfire really does run up to its full potential. Metro 2033 for example should make great use of all 4 GPU's

There is also the question of power draw. You need at least 850W PSU to run two 6990 and a OC'd CPU. To really have a proper head room to OC the cards as well you be safer with a 1000W unit.

Mean while a 750W PSU is more then enough for 580 SLI.

What's better for work depends on the software but in my experience nvidia tends to be better supported generally. Productivity software also tends to be limited to one GPU so the faster single GPU performance of the GTX 580 also come out on top in that regard.

So they both have pros and cons. One is not outright better over all then the other. For the best possible gaming performance the two 6990 win but the GTX 580 SLI has a lot of good points to.

Test the difference? smile.gif

6990 CF will get very, very loud under load compared to the custom 580 sli setup, thats for sure..

Thanks for your reply, do you say 6990 quadfire because they are dual-gpu cards right? Can I use crossfire and sli together on same motherboard? just wondering :S

Wont have a problem with power due to picking up this beast..the CPU can pull a bunch of power overclocked aswell.
