Why don't you try the ATi Radeon 9600 Pro? You could get a 256Mb version for that, I have the 128Mb one and it runs games really well... Condemned: Criminal Origins can run with really good graphics, all on medium/high (without dynamic lighting/shadows). So can Tomb Raider: Legend, Need for Speed: Most Wanted etc. I had an issue running Ghost Recon: Advanced Warfighter though
.
It can run Half Life 2 with all graphics on the full with bilinear filtering & anti-aliasing at 4x
