Recommended PSU support for HD 5770: "450 Watt or greater power supply with one 75W 6-pin PCI Express power connectors recommended (600 Watt and two 6-pin connectors for ATI CrossFireX technology in dual mode)"
Great! Thanks WR2, I just bought the MSI 890FXA board from newegg for $119.99! They changed the price back up the next day to $200.00. So now I have this sweet crossfireX board that can do x16/x16 or x8/x8/x8 or x8/x8/x8/x8. I only have one 5770 for now, but I just want to make sure that in the future, I can upgrade to two. Thanks again
