I am wonder if it is possible to run 4 cards on a Gigabyte GA-990FXA-UD3 motherboard?
And if it is.. How would that work?
I know i would have to get powered risers and raise them up..
an adequate PSU
But is that it?
Just plug them in..
Install drivers on Win 7
and go?
Yes, you're exactly correct. You should use at least one powered riser or two to be safe. Also invest in a quality power supply with more than your minimum required wattage.
I exact have the same motherboard on one of my rigs with a Corsair AX1200. Just don't forget to disable any features on the mobo in the BIOS that you dont need (firewire, sound, etc.) to save a bit more power.
