That PSU is good also, but the others I posted here are better quality.
Here is a more affordable one that is very high quality,

As a side note, most OCZ memory is incompatible with the newer P965 chipset. I would avoid OCZ ram.
If he is overclocking I would avoid any chipset other than the 965 or the 975. All of the others have a FSB wall and his OC will be severely limited. If he is not overclocking then the other chipsets are fine. If he is going SLI he is out of luck, most of the SLI boards will not OC very high at all.
If you wait just a little longer you will see video card prices drop because DX10 cards are starting to arrive.
PS: Trusted brand names for power supplies are Enhance, Seasonic, Sparkle, PC Power & Cooling, Enermax, Silverstone, Hiper, and Corsair. The newer Antec (NeoHE) and Thermaltake (Toughpower) models are good. That XClio model is good. Anything else and I would not trust it with a >$600 PC.
