Actually, the board only has 1 PCIe slot capable of handling a graphics card - no matter, that is all you need. Dual video cards are for high end machines. Your budget is a bit low for any performance for video editing, but if you keep things simple, it should work fine.
Thanks for those details. I actually have a WD 640GB SATA drive and DVD burner that I will more than likely transfer. As of right now, I cannot recall what connections they are, but once i confirm that, I will just transfer them. I also have Win7 Ultimate 64 bit, so i am good there.
