well, a good geforce 4 ti4200 is around 130 bucks right? well you can get a geforcefx 5200 ultra for another 10 bucks extra, get similar performance to the 4200, but still getting the "optimized" directx 9 portion(since he plans on playin doom 3), and once games start coming mainstream in directx 9, you're 4200 can push out the frames but not the quality...
