CPU: Intel Core 2 Duo E6300
Mobo: Gigabyte GA-965P-DS3
RAM: OCZ Gold 2GB (2 x 1GB) DDR2-800
Video: Forget Crossfire altogether. Crossfire and SLI are both completely pointless unless you are going to be gaming at resolutions over 1600 x 1200. Go for an eVGA Geforce 7900GT KO Superclocked
Optical Drives: Drop the Liteon drive. The Samsung does everything the Liteon does and more. There is no reason for anyone to ever have more than one optical drive anymore.
CPU Cooler: If you actually do get a Core 2 E6300 chip, drop the aftermarket CPU cooler altogether. You won't need it unless you're going to be doing A LOT of overclocking.
