Is this a god system for gaming?

For gaming the GPU is much more important than the CPU

I would get a Phenom II X4 955 + HD 5870. And a 550-650 watt PSU.

Take a look at the sticky HOW TO ASK FOR BUILD ADVICE and post back with some more info, like the OP said for gaming thats not a well rounded PC.

Also with a X58 mobo you would be better off with 3x2 gigs of ram for 6

860 watt PSU - what kind?

For 2 HD 5870s in xfire with room to OC the CPU i would go with, a nice Corsair 750w PSU

But to we get more info about the monitors rez and if the OP cares to xfire

This is all just running the mouth input
