I would get a better power supply. That one doesn't have much 12v amperage compared to a quality corsair or seasonic would. Also why 6790's? Those are quite outdated at this point.

It seems that you have enough power for your build, I don't think you will need to worry.

Try the link, since you are the one who knows what will be plugged in at all times. But it is wise to avoid the budget cheap brands since they are not very good. Try Seasonic, Corsair, XFX.

(Note this is the Minimum Recommended amount, try to have about 50-100 more watts)

Well i was running a single EVGA 512MB 9800 GTX and a friend sold me 2 of these both for 100 bucks, so I couldn't pass it up, and the only games I play are diablo 3 and dirt 3 for now.

That is a nice PSU. I have the original version and it has been great. $100 for both cards was a steal. Just wanted to make sure you weren't buying them new. :D
