If I can have a 8800 gtx, q6600, and the case I showed with everything else included (mobo,psu,memory,etc) under $1500 that would be awsome if not oh well
For the graphic card. What resolution, do you plan on playing games at? If it's below 1680 x 1050, just go with the 8800GTS 320mb, and upgrade to the 9 series later.
If you plan on upgrading to a Penryn, get the e6750, to save you some money.
That looks like a great case. Everything will fit. Just pricey for me, but that's your choice.
You can order stuff, but wait for the C2Ds to drop.
if i were you i would just get a GTS 640MB it will play any game out there right now at high settings and will play upcoming games at med-high settings just fine, this will also save you a good amount of money
The thing I can see you cut down on, is the 8800GTS 640mb, down to a 320mb, since you're playing under 1680 x 1050. The 320mb is still a great GPU. You could also cut down on the case, but it's your personal preference.
