Reminds me of my build I did about 4 years ago. Yours is bound to be better and faster, because of the newer parts. So far, the only problem I've had with mine, is 1) I'm on my 2nd mouse, 2) Occasionally I don't get any video output on a power up. When this happens, I have to hold the power button to shut it down. Wait a few seconds. Then power it back up. I always have video the 2nd time. This happens, about once a month.

Maybe I should pull the cards, then reseat them.
