One thing I do suggest if you're a HD junky is to get the 73 gig SATA raptor. This is the fastest drive on earth today.

For my space eater drive I use a 250G Sata Deskstar (7200 RPM 8 Meg cache).

IMO the 6600 GT offers the most bang for the buck in a video card today. In certain games Dual 6600 GT WILL outperform a 6800U. True some games/apps don't take advantage of SLI and that's when the single expensive card will win.

If you're looking for an awesome heatsink I would suggest one of the thermalright models with the heat pipes and all copper construction. It's gonna be heavy but you cannot beat the cooling power without going to exotic water cooling solutions... or if you really want to drop the big bucks phase change technology.

BTW I DO plan on playing in ultra settings. I would be putting my horsepower to waste otherwise! LOL.

Gonna have lotsa fun OCing with the Lanparty board too. The CMOS reloaded feature is something I am really looking forward too. I will post pictures of the system later.
