Mini-ITX Cheap Gaming Rig

[Sir_Great]

What CPU and mobo(Wifi required) do you guys recommend for this setup?

RAM - Kingston HyperX Blu 8GB 1333Mhz DDR3 CL9
Power Supply - OCZ ModXStream 500w
Case - Lian Li PCQ08
Graphics Card - Sapphire HD6850
HardDisk - Hitachi 500GB 7200/16M HDD
DvDDrive - LG GH24NS 24x Sata DvD

I am trying to make this setup as cheap as possible but I am trying to keep
all parts of the system as gaming components

I think AMD would be cheaper but the thing is, I know nothing about AMD which is why I need all of you guy's help

I would really appreciate the help and sorry for the bad English - I can't be bothered to think of the right words to use
