AMD 790 FX/GX/X

[gammaray]

which one should i get to put a X2 dual core with a 4670 ATI video card

Also, any brand recommendations, with models?

from what i understand, the 790FX has the 600SB while the 790GX has the 750SB, big deal?
and the 770 has the 700SB. This is a little bit confusing.
i need one pci express slot, a good OC Mobo.
