    I'm wondering if I can run two 5770s off my motherboard, or if it's a big waste of time and money?

    According to the website my motherboard has:
    "Expansion Slots 2 x PCIe 2.0 x16 (*[email protected] x16 mode, [email protected] x4 mode)
    1 x PCIe x1
    3 x PCI
    Storage SB710 Chipset
    1 xUltraDMA 133/100
    5 x Serial ATA 3Gb/s Support RAID 0,1,10
    1 x eSATA 3Gb/s ports"

    I'm assuming that it would need two [email protected] in order for it to work? What is x4 used for then?

    well, you could, but running one on 4 lanes would cause them both to run at that speed (slowly), so yeah it'd be a waste of time. If it was 2 slots with 8 lanes each it'd be fine, but 4 is a performance killer. Sell the one you have and buy a 5850
