honestly, most people are now getting tricked into buying dx11 card as soon as possible just because they have dx11 support. the same mistake they made on buying dx10 cards at launch. they never learn. from my understanding the only big advantage dx11 has against dx10 is the hardware tesselation support. and even that is not going to be too noticeable while playing the games. the player would be too busy playing the game than just looking around and focus on the tessellation effects anyway. maybe slightly better shadows. the difference will not be like night and day for sure. I own a 9800gtx+ and will keep it as long as i can play games with it. DX11 wont affect me.
