I've heard good things about some of the higher end ATI cards recently, but I'm an nVidia person, so I wouldn't be able to help specifically.
Right now I'm thinking about either a pair of 1 Gig GTS 250's for $99/eachor a single GTX 465 for $250I know the smarter choice long term is the GTX 465 so that I can put it in SLI later...but lets be honest, if I'm not using the SLI configuration now, I'm not likely to do it later when the next shiny comes out. It does support directx 11...but do I really care?Are there any other cards that I should be looking at?
