Hello, can anyone tell me the wattage of the PSU I need for the following specifications? I'm thinking 600w but it may be a little overboard and I don't want to waste electricity.
Processor: Intel Core 2 Duo E6600 Conroe 2.4GHz
Motherboard: EVGA 122-CK-NF63-TR LGA 775 NVIDIA nForce 680i SLI ATX Intel Motherboard
Memory: CORSAIR XMS2 DOMINATOR 2GB (2 x 1GB) 240-Pin DDR2
Hard Drive: Seagate Barracuda 7200.10 500GB 7200 RPM SATA 3.0Gb/s
Video Card: EVGA 320-P2-N815-AR GeForce 8800GTS 320MB
Sound Card: Creative Sound Blaster XtremeGamer 7.1
Optical Drive: Lite-On
Case: Aluminum body ATX Full Tower
Also, is the GeForce 8800GTX worth the 300$ more than the 8800GTS 320MB?
