Nothing wrong with the 9600GT if you are on a budget and need to cut the fat somewhere.
500w is more that sufficient for this system. He isn't running multiple video cards, hard drives, etc.... I am not suggesting that he go out and buy a cheap POS power supply but he should not go over board and buy a ps that is beefier than he needs. Save money on the initial purchase and the electric bill!

You should not be building a computer if you can't use the MB's bios. Overclocking on this motherboard is as simple as changing one or two settings. You don't have to mess around with the voltage and good 500 - 700 mhz overclocks can be achieved with the stock cooler and more than reasonable temps.[/quote]
Very good find on the motherboard ... I must of skipped over it for some reason. I will add it to the dummy build I'll make for him.
The 8800GT is more then likely the best choice for him if he can spare the money, in the end we should simply just say the 8800GT is better, but 20$ more in cost then the 9600 .. then it'll be up to him if he can afford it. The 8800GT does do better by at least 10+ FPS then the 9600GT though.
Overclocking is very dangerous even if you know how to use your MB's bios. One wrong setting can seriously damage components. Sure mess around with it at first and get a small amount of overclocks with no voltage change, but that still takes research on how to do it and can be confusing for some if not most no matter how basic it can get. Even if the user has done a ton of research, I wouldn't recomend overclocking. Then again, I would never recomend overclocking to anyone due to the fact I don't want someone to hold me accountable for their mistake.
That PSU calculator comes dangerously close to that 500w mark
Core 2 Duo CPU
High End Desktop Motherboard
8800GTS
1GB DDR2 RAM x2
1x Optical Drive
1x Hard Drive at 7200 RPM
This comes out to 432w ... Subtract about 10w for the GT so around 422w would be recomended. These numbers do not include case fans, USB devices (such as an MP3 player, mice, and keyboard), a CPU cooler (which I'd recomend, especially if overclocking), or any other devices that plug into the computer. So a lowball amount of about 430w in the end with all of the extras. Leaving only 70w for future upgrades, such as more RAM, another hard drive for more space, and other possibilities, like overclocking. So yes, you can say a 500w PSU is good enough, yet it's getting dangerously close. Lack of power can cause heat and hardware issues, the two leading causes to early PC death. Plus in my build, he's getting a 600w PSU and a case for only 10$ more then your estimate. Leaving him safe for upgrades and future tweaking.
I would also like to mention my prices were a bit highballed because I didn't want to under price something for the OP. I will list the parts later on, the OP can sort through them if he wants. I will use newegg as a site just for information. Where he buys them will be a different story, it should give him an accurate price in the end though.
