I'm attempting to put together a computer and right now im looking at part choices. I think i have all of the necessary parts but I'm not sure if the RAM is compatible with the mobo, and if anybody has some suggestions to replace some of the parts for cheaper or better parts they would be greatly appreciated. My end goal is for the system to be able to run games such as Diablo 3 and more advanced games. Here is my list so far.

Motherboard Asus LGA 775 ATX Intel Motherboard

Processor Intel Core 2 Duo E7200 Wolfdale

Video Card EVGA GeForce 8600 GT 512 mb PCI xpress x16

Power Supply Antec 650W ATX 12v
http://www.newegg.com/Product/Prod [...] 6817371015

RAM 4GB Gskill 240-Pin DDR2 SDRAM 1066 (PC2 8500)
http://www.newegg.com/Product/Prod [...] 6820231166

Hard Drive Seagate 250 GB 7200 RPM Sata

Case? Sunbeam ATX Full Tower (wasnt really sure what would or wouldnt work here, if there is something cheaper that will work just as well i would prefer it)

With the RAM I wasn't sure if the SDRAM 1066 would be compatable with the Mobo, since the Mobo says Memory Standard is DDR2 1200. However, since they are both 240-pin shouldnt the 1066 RAM work?

Thanks in advance!

So so first of all change the Video card not DDR2. I would take the antec 500. Get 4GB 800MHZ

ok i replaced the video card with an XFX GeForce 512mb DDR2 video card, replaced the 650w antec with a 500w antec, and changed the 240-pin DDR2 RAM from 1066 to 800 speed. Thanks for the reply, anybody else have some suggestions?
