q8400 and 9500gt?

[Schall]

Well, my psu is fried so I'm getting a replacement. I also decided to upgrade some other components. I'm on a 250w, 1.8ghz single-core, an old nForce(I think thats it) mb, and a 9500gt video card. My main question is: does anyone know of any online benchmark tools that I can select components to benchmark instead of benchmarking my own? I think I'm going to get a q8400 cpu.
