PSU watt whores are people who make me mad. Just becuase PSU's like OCZ label their 600 or 700w models "Gaming" everyone thinks that 600w's is needed on every model.
It has been tested that an 8800GTX can run on a FPS 400w.
I always say get a 500w PSU and that's all you will ever need unless you go SLI.
