Well actually my problem was with the motherboard tray. Since the tray only has one slot for that 3rd card it wasn't seeding correctly. I had to bend the backplate on the card to have it fit correctly and it recognized the card. I don't know about this setup though. After about 30 mins of folding the machine will just cut off. I'm thinking its a heating issue or the fact its a 900W PSU and drawing 860W is putting too much stress on it and killing it.
