Recently I had an ATI 4850 Radeon GPU die on me after about 6 months use. I have RMA'd it back to Newegg and expect a refund because they no longer sale that card. Looks like GPU prices have come down quite a bit since last October. Looks like my replacement choices include either an Nvidia 260 (216 cores), or an ATI 4870. Right now I am leaning towards the 260, however, I am concerned that Nvidia cards only support DirectX version 10, while ATI cards support version 10.1. Wondering how that impacts me in the future. Windows 7 will have DirectX 11.0, so will I be at a disadvantage with an Nvidia 10.0 board. Appreciate the education you may be able to provide. Thanks.
