Even at Triple Screen resolution the GTX 680 beats the 7970....and it does it with a smaller framebuffer and less memory bandwidth. In most tests, it looks like the GTX 680 is beating up on the 7970....and it does it for less money I believe.

WOW!

I wish the 4GB model was out. At 2560x1600 with high settings, X-Plane 10 is getting pretty close to 2GB.

*EDIT* Looks like it uses less power and produces less heat than the previous generation as well. It seems like the GTX 680 is the ideal card, especially if you don't run at 2560x1600.

Good review of 3 monitor performance. Eyefinity performance is important to me. Thanks for the link.

At the end of the day, Nvidia fans can justify GTX680 and AMD fans (like me ) can justify HD7970. Hopefully, this will lead to a price war benefiting all of us

FXAA.... the Image Anti-Aliasing Engine is that Much faster on a Single Screen, times that by 3...

not to mention the auto overclocking to 1.1/1.2Ghz, which cannot be disabled.

when the HD8000 Series comes out later this year with FXAA instructions, AMD will take it back.

Great review, thanks for passing that on, really surprised that the 2GB VRAM did not bottleneck at 5760x1200, they must have some better way to move textures in and out of VRAM so it is not as big a deal as before.

Very interesting info after all the months of rumors and leaks.

looking at the graphs, they trade blows in some games either card being 5 to 10 frames better,

but the games/scenerios the 680 wins, it wins by 10-15% (15-30 frames/sec)

that gap would be smaller had they overclocked the 7970 to 1.1Ghz to match the turbo of the Kepler.

once you hit the games that dont like FXAA, AMD matches and beats kepler at 300Mhz lower clock.

Most of the games are even in 3 screens (within 5 frames/sec of each other.)

except for Elderscrolls,
DeusEx had higher numbers, but wasnt able to run max settings, where as the AMD card was.

they trade blows in the power consumption and are about the same temperature wise.

Basically nVidia waited to see what AMD had and setup their GPU to beat it, which it does in tesselation and FXAA.

Hopefully AMD realizes this and lowers prices..

ps 170 frames/sec vs 180, you wont notice as most LCD screens are 60/75Hz (unless they are 3D, in which case they are 120)

I think it is pretty significant for the 680 to match the 7970 in 3 screens resolutions.

I was hoping for single card support but expected NV to lag behind on ATI on 3 screen gaming without SLI due to their late arrival at the party. But the fact that they can go toe to toe and both cards do a good job is really great news overall for all of us who desire 3 screen support but the developers of games always saw it as some niche ATI Eyefinity feature.

Starting today this is now a standard feature of both companies and I bet it will really become much more mainstream, woohoo! really good news for those of us who like driving and flying sims, iRacing on 3 screens is awesome and I can only hope more to come from other sims.

its good news as both cards are basically equal, one does better in some games, while the other does better in the other games...

bring on the Price wars, my rig is crying for a 2nd 7950 for SLI, haha

Or bring on the Atomic, or Lightning, or whatever 1.3GHz clocked cards are hiding in the wings.

when I saw that the 680 is doing 2x FPS than my 6970 in BF3 I was
