Yeah, I went with a 790X because the FX was a little out of my price range for the Giga and Asus boards currently available... and I only have one video card and doubt I'll crossfire it. I skipped looking for a GX because I don't need the onboard video and thought maybe it would add additional heat to the NB.

BTW, those are awesome results on that 720 you've been playing with. I read that this morning and it just sealed the deal on my purchase.
