His score is very very good for an ATI 7500. Comparing it too a gf3 is not even fair, maybe a gf2 ti would be a better comparison
I'll say. I have my GeForce 2 GTS and CPU overclocked moderately, and my RAM pushed pretty hard, and the highest I've gotten is around 4300. I have a few bottlenecks in my system though. But anyhow, with a DX7 part like he and I have, 5100 is a pretty darn respectable score on a DX8 test.
