Looks great, so this is what my build looks like now:
CPU: i5 2500k
GPU: 2X GTX 480's
Ram: 8GB (not sure about brand yet)
Mobo: ASRock Z77
Case: Corsair Carbide 400R
PSU: 850w (brand not decided but I think I'll go with your suggestion)
I know this is missing a few components but I'll get to them at a later date.
Is this a good build??
Thank You so much for you help, you've done so much to help me
