I'm not getting vista. Price is too high and it will eat up resources like no tomorrow. I'm gonna ride XP until it dies out or possibly just get a mac and vista basic to dual boot with. I think 400 dollars for windows is too much, microsoft is taking advantage of consumers in my opinion.
Until there is actually a DX10 game that interests me enough to make the jump (which will be major considering the hardware required) I'll stay with XP
