Your argument stating that a 7970 OC'd wont beat 2 560s in SLI? Rofl. A 7970 can match 6990 performance when OC'd but can't handle 2 560s... right.And in regards to your statement about 'shooting a frame that doesn't exist anymore' when not using Vsync. That absolutely makes ZERO sense. The amount of time it takes for a frame to refresh is MUCH quicker than any human's reflexes, so even with a slight screen tear for 1/60th of a second won't mean jack.
I can't play BF3 without Vsync, single card or SLI/Xfire, I play on a normal 60hz montior, and if the FPS rise's above 60FPS in BF3 I get wicked screan tearing, I mean WICKED screwn tearing, to the point where playing is impossible let alone competative game play. This effect is removed compleatly when vsync is on. and its not just my rig, my back up rig and a few of my friends rigs, same thing. With a standerd normal 60hz monitor screen tearing happends above 60 FPS.
If you dont know, Screen tearing is when your monitor cannot refresh fast enough to keep up with the incoming image's from the video output. Its a common issue. Unless your suggesting that every human has a 120hz monitor.
