I received everything except the frame and risers, so I've been playing with two cards on the X16 slots.

Between Windows freezing, the WiFi not working, one of the cards not beeing recognized, this and that, I can't believe how often I've had to restart the computer. So, if you want to stay sane:

DO BUY AN SSD, PEOPLE!
It's well worth it, just for the restarting time.
