Tessaltion- Not much games utilize this yet and from the games I saw, it's nothing to brag about yet...
All DX11 cards have tessellation. Its a requirement. Southern Islands is supposed to greatly improve ATI's tessellation performance.
Right. Cause 3 monitors is somehow not a gimmick while 3D and PhysX are? Come on dude paint it with the same brush if you want to go that route.
Well, PhysX is a gimmick because nothing uses it.
3D could be seen as a gimmick and Eyefinity not if you don't like glasses. 3D also requires 120hz monitors, which aren't cheap.
Besides, with just basic Eyefinity you still have 3 monitors for desktop usage - which is awesome. People have been running dual and triple monitors for non-gaming purposes for many years now, so depending on what you have and what you want, I could see considering 3D and PhysX gimmicks while thinking Eyefinity isn't a gimmick.
