Looking for a cheap PCI-e quad card. I'm building a machine for a guy and the motherboard only has one PCIe x16 slot and the rest are x8. For the money I'd spend buying either non-matching (which i don't like) or a matching card I want to look into a decent 4x DVI quad card. Ideally it will be a little older, proven, tried & true, etc. Just need a no frills solid quad card. Nothing special or fancy, the equiv of an NVS 290 or similar. Any suggestions? Budget is as cheap as possible, hopefully under $50. (ebay, used).
