Note: This is has the faster DDR3 memory & is AGP (NOT PCI-E)
Overall performance/FPS is on par with a X1650Pro: http://www23.tomshardware.com/graphics_2007.html?modelx=33&model1=721&model2=735&chart=318,
but costs considerably less
This would make an excellent upgrade in an older AGP PC that doesn't have very good graphics. Minimum CPU required so not to cause potential bottlenecks would be an Intel P4 2.6 or AMD Athlon XP 2600+ (I think). Just make sure you have a good quality 400-500W PSU at the very least too.
