need a mobo with crossfire and a pcie 4x at least.

So I got a RAID card, 3Ware 9650SE-4LPML only supports is PCIe x4, so it must be used in a PCIe x4, PCIe x8, or PCIe x16 slot.

I didn't realize but the mobo I got( gigabyte x48 ds4) only has pcie 1x ports I tried putting the raid card in the 2nd pcie 16x videocard slot but it was having problems. I called their tech support and they think that that pcie16x can't support the card since its used primiarly for crossfire.

Do you guys have any recommendations on a crossfire board that has another pci-e 4x(at least) slot. Or maybe I could go with a p45 board like ASUS P5Q Premium LGA 775 Intel P45 ATX.

What do you think I should do? is the p45 performance as opposed to x48 in crossfire really that crippled? I heard there wasn't too much of a difference.

i luv my lanparty dfi x48 ut t2r , , it has 2x16 pci-e and 1x4 pci-e at the bottom + a pci-e x1 just below slot1 but this isnt really usable as most modern gfx cards block it. depends how much your willing to spend tbh though.
