PSUs run most efficiently at 50-75% load. The energy efficiency of power supplies drops significantly at low loads. It is a good idea to buy a power supply such that the typical load wattage from the computer is 60% of the rated value of the PSU provided the maximum load wattage does not exceed the rated value of the PSU. Many OEMs design systems around this idea.
Thank you, that's a good point on the psu area. I really think he should look more towards a mid range card, or get a seccond card like he has and run sli. The 9500's are cheap and both run dx10 which should be good for a couple years. =) Dropping another $50-$70 now and saving the rest wouldn't be a bad idea. Or wait till the next gen DX11's come out and drop in price.
Oh and that 200W on my previous statement was without GFX.
