I had the same configuration to you except with a 6600GT 128mb and a Barton 3000+ and it worked fine: PSU stats were:
12v = 16A
5V = 30A
3.3V = 20A
Total output on 5v and 3.3v - 180W
Although thinking about it, I only ever got 7500 3d marks 03, and that PSU for some reason failed on me (now It turns off after 3 seconds, but only if it's plugged into my HD). In fact even worse, since then my 6600gt won't output anything through any of the outs, so im back on my old nvidia TNT2.
So, er anyway, all in all I can't say I'm sure. You're current PSU seems more suited for the job than mine was.
