New Mobo/Rig

[Jonnygrunge]

Thinking of a new mobo for an Intel Core 2 E6750. I've always been an AMD/ATi man in the past so this is all new to me!
Thinking of the EVGA nForce 680i SLi will it be ok with OCZ PC2-8500 RAM @ 1066MHz? can some one please help/advise me on my purchase? Should I go for nVidia or Intel's P35 chipset?
My new rig:
Hiper 670W PSU, will my Hiper 580W be OK for my new rig?
EVGA 680i SLi
Deskstar 500GB SATA II
OCZ 2GB PC2-8500 RAM
BFG GeForce 8800 GTX OC2 768MB GDDR3 VGA
Intel Core2 Duo E6750

Should I also make the switch to nVidia for VGA? or go for the HD2900XT?

Thanks in advance guys!
