I smell spam......

If a 7970 can match a 6990/590 with a decent ('ish) overclock I doubt your Ti's were faster rolleyes.gif

Not in BF3 with no AA. 99% of benchmarks in the Internet show BF3 in Ultra with 4x MSAA. If u disable it HD 7970 is like 25% faster then HD 6970. HD 7950 is even slower then GTX580. If OP is not using AA which he did state then GTX560 will be faster even after OC.

Activating 4xMSAA in BF3 running at High + Ultra textures drops performance from 120 fps to <70 fps for me.

Also, according to Anandtechs review of the 7950, the 7950 takes a bigger hit than the GTX 580 when activating 4xMSAA. The deferred shading isn't playing nice with AMDs GPUs

At a mere 1GB of Vram for the 560's, they are also at a great disadvantage versus the single 7970 and it's 3GB. Good luck trying to run 4xAA at all utlra settings with SLI 560's smoothly. A decently overclocked 7970 should match up quite nicely with 560's in SLI. With a relatively heavy OC, the 7970 should beat it no problem.
Edit: didn't notice OP mentioned 2GB, still 3GB >> 2GB in BF3.

Why does everyone get hung up over vram and fps?

Vram doesn't do anything to fps, all it does is reduce stuttering in games that use a lot of vram.

Plus these results shouldn't be surprising at all, especially since AMD cards do not fare as well as nvidia cards with 4x msaa in BF3. I would take 2 560ti 2gb's in SLI over a 7970 any day.

AA kills AMD cards. if you disable it that thing will fly. Why anyone needs AA at your insane resolution IDK.

Why wouldn't you want to max out AA?

Especially if you are going to drop $550+ on graphics.

I read up to the part where you mentioned Vsync, then realized that our tolerances for input lag and micro-stuttering are completely different (I do not tolerate either in the slightest bit).

Vsync is a crime against human-interface-devices.
