I'm in the planning stages of purchasing a computer for me when I head off to college for work and play. Now, I've really considered the ATI X1950XTX 512mb card. It has great reviews and specs and can play every game out there at the moment. However, with Vista around the corner, will I not be able to play the new PC games that come out this year? (i.e. Halo 2, Supreme Commander, Bioshock) Because of Direct X requirements, will I have to purchase a Direct X10 card JUST to play Direct X10 games, or can I use my ATI?
