oh hell, i dont need to upgrade my geforce 5700 LE, it rocks!!! n it's better than the 8800gtx! (sarcastic) i run games at 1x1 resolution, n wow, the fps goes up to infiniti!!! i told u my card rocks... (realistic) i cant get the game to run at maximum settings with 4xmultisampling on 800x600 higher than 6fps, am a graphics quality freak more than a performance geek... but still, my card ROCKS =]!!!!

i read in a customer review at newegg.com on the x1950 xtx that -quoting : "Just wanted to clarify an apparent misconception here: Windows Vista does not require a DX10 card. Their WDDM driver works just fine with DX9 series cards. Also, be aware that the chief addition to the DX10 specification set is a new focus on using shader processors over pixel processors. These cards, though not DX10 compliant natively, are designed with heavy shader use in mind and will likely be software compatible with DX10." but who knows!!!!
