Is this a decent build for a gaming PC?
Intel Core 2 Duo E8400 Socket 775 (3.0GHz) 1333FSB 6MB L2 Cache Retail Boxed Processor
ASUS HD 4870 512MB GDDR5 Dual DVI HDCP HDTV out PCI-E Graphics Card
Samsung SH-S223F 22X DVD1RW/RAM/DL Serial ATA Black Bare Drive - OEM
Antec 300 Three Hundred Case - No PSU
Kingston 4GB (2x2GB) DDR2 1066MHz/PC2-8500 HyperX Memory CL5 Unbuffered Non-ECC
Western Digital WD3200AAKS 320GB SATAII 16MB Cache 7200 RPM - OEM
Coolermaster RealPower 620W Modular PSU - SLI Ready
OR
Coolermaster IGreen 600W PSU - 85% Efficiency 8pin ATX12V v2.2 120mm Fan
In particular i'm not sure about the PSUs. I'm fairly sure that they support SLI, but will that be OK for Crossfire and which one of the two would be better?
