2560x1440 resolution

yes i guess i could try that, thanks for the tip

Never thought about that before thx

Hmm, i see there is a 4gig version as well of the gtx 680.

Maybe this could be the best option for high res.

Indeed!
And here is the link to the benchmark which explains how performance drops on a 2Gb GTX680 card when the VRAM is overfilled:
http://www.hardwareluxx.de/index.php....html?start=16
Using the game SKYRIM they increased MSAA & SGSSAA in order to fill the VRAM (they could have just easily fired up CoD and flown over London... )
2560x1600 res & 4xSGSSAA 1918 MB VRAM
2560x1600 res & 8xMSAA & 2xSGSSAA 3100 MB VRAM
2560x1600 res & 8xMSAA & 4xSGSSAA 3127 MB VRAM
2560x1600 res & 8xMSAA & 8xSGSSAA N/A MB VRAM

The drop in fps of the 2Gb GTX680 is impressive!


Keep in mind though that the same effect you will probably achieve with a GTX580 3Gb!
So your real issue is how to get a card with more Gb VRAM than the 1,5Gb you have now.
For sure the GTX680 is more performant than the GTX580 but how much is the price difference you only can decide.
I still stay on my recommendation that you try to trade in your currect GTX580 for a GTX580 3Gb as the best value for money.

PS. I still think that the GTX680 is not the real card for CoD because of the "lousy" memory interface of 256bit...

Nice and good but it also has a disadvantage just to add some more vram onto a originally designed 2 gb card as already seen in the 3gb version of the 580. Furthermore there is still an over 5 year old small interface for this and the 4gb version also suffers from that.

Fact is that a 7970 ghz edition is currently in most cases as fast as a 680 and the review shows, that this overall is currently the fastest single card. Sure the pace is often only marginal, but we have several 680 users bite in their asses, that they bought it, because it is unfinished and expensive.

The 7970 users are quite happy now with the new drivers. 680 users not always. Just our impression of a small clan comunity with about 100 people. Some are benchmarkers as well and now tried out for months. It has a reason, why the review of the 7970 changed places in many cases in the race of the best single card.

I must say, that we are still waiting on a big kepler. If that hits markets somehow, ati will have quite a big problem. But for now the ati is more than just an alternative card for the 680. My opinion and the opinion of many.

Hmm im more a nvidia guy, i have had some ati cards before but i like nvida better. So i think it will be a gtx 680 4gig. But thanks for tips.

Have any of you tried SLI in CLOD, i read in some other post that it isnt realy supported.

I will come back to this post and update if i buy the 680, tell you frame rates etc.

Y E S! P L E E E A S E!


I have SLI, yes it works but no it does not. You get a good boost in fps but, there is a kind of stutter that can not be explained by words, it makes the movement unsmooth. Subsequenly most sane people drop the sli and use a single GPU only. Less fps but smooth game.

FPS is not what you should be going for (after you have reached above the 30fps of course).

I have 2560 x 1440, 2 x 580s in SLI and get similar to you.

apparently when Nvidia release proper, tuned, drivers for CLOD on SLI we should get higher rates, I'll wait and see. I have no problems with 20-30 FPS near the ground, its the collapse to < 10 when sprites are shown (grass, dust, smoke etc) that concerns me. Using FRAPS is also a FPS drain thus no more videos from me until performance improves.
