...i too used my TI4200 for a few years before i even thought i would need a GPU upgrade, had no hints of slow performance in the games i played, granted, they were several years old themselves (diablo ii, unreal tournament, unreal tournament 2003, warcraft 3, etc)... then i tried playing doom 3, THAT convinced me i needed a new gpu, because the performance, even on low, was choppy, and the image and rendering quality was subpar... so i opted for a 6600GT, and everything dramatically improved, so ive been trying new games since then, and since upgraded my card again when i changed platforms from s462 to s939 recently... so yeah, the TI4200 is great for older dx8 games... but youre definetly better going for a 6600GT for anything released in the last couple years, definite improvements all around, many times over
