I have a ASUS P6X58D-E motherboard running two video cards. Due to the size of them I would rather run my 5770 in the PCI-e 2 slot and my cheaper 4650 in the PCI-e 1 slot. For better cooling of the 5770. I have tried it both ways and performance is nearly identical. I run 4 monitors two main on the 5770 then a couple of small cheap ones on the 4650 for TV and email. Is there any way to control what monitor the bios comes up on? If I flip the cards it pulls up on one of the small monitors with one of the big monitor resoluations so I can only see part of the screen.
