This would run circles around the video card you picked for only $10 more and has excellent cooling...

Might need a better PSU though...

That setup is pretty good. The graphics card itself is good although you could do better price/performance wise.

I don't know how good the quality of the psu so i don't know whether you can run 8800 series card and other components combined or not, if its generic then probably not, so you should check that out.

My Seasonic S12 430w is good enough for the 8800gts so its not all about the watts, it depends.

Overall the setup looks very good.
