frozR 3 seems to be the one to get, even if it fails to flash its got a backup BIOS so you can recover.
When the graphics card is installed, how many free PCI/PCIe slots am I going to have? I assume it'll take up 2 slots + leave 1 empty for air flow so with the MSI GD65 I'd have 1x PCIe and 2x PCI free, does that sound right?
