I picked up my power supply today and got it installed. I found my system was running the card on a 300 watt supply. After I rerun all the bench marks this is what I found. The lower power supply was slowing down my process a little. On both 3d programs, the cpu test resulted in a 0, and with the new power supply, it recieved 2's. As far as RF goes, it keeped the frames about the same. After I tested every thing, I overclocked my card to these settings, 560/710, over the stock 500/690 stock configuration. This resulted in 90 fps on the ground and 95 in the air. So I gained about 5 fps overall. So this just shows, you can use a 7900 GS with a small power supply and get good results. I am not sure if this will reduce the lifespan of the card or cpu. But it works great.
