Thats why i never buy from the BIG GUYS. I build my own to get what I WANT and pay HUNDREDS Less. The price these guys sell dual cores and quad cores you can build high end gaming computers cheaper.

Phenom II x4 955 BE 3.2ghz@ 4.2ghz
ASUS M4A79T Deluxe
8GB OCZ LV gold edition 1600 1.65 8-8-8-24@1740 17.44 1m
Coolmaster Case w/Corsair 850w PSU
4870 1gb Sapphire Crossfired
Thermaltake SpinQ Idle 31c Load 44oC

Cost me just under 1700.

Now a build like that from dell or hp would be well over the 2500 mark.
