The PC I intend to build:
Asus M4A79XTD EVO AMD 790X Socket AM3 Motherboard and AMD Phenom II X4 840 3.2GHz Quad-Core Processor Bundle
XFX HD577AZNFC Radeon HD 5770 Video Card
Corsair 4GB DDR3 RAM (4GB enough?)
Western Digital WD20EARS Caviar Green Hard Drive - 2TB, 3.5", SATA-3G (2TB excessive?)
Ultra LSP550 550-Watt Power Supply (enough?)
Lite-On IHAS22406 Internal DVD Writer - DVD+R 24X, DVD-R 24X, DVD+RW 8X, DVD-RW 6X, SATA, Lightscribe
Thermaltake V3 Black Edition Mid Tower Case
OS would be 64bit Windows7 and I should have some keyboard/mouse lying around.
The total cost would be around $600.
Have I chosen the components properly and is there anyway to make this cheaper while still being a decent gaming pc?
