PCI-Express is backwards compatible, so it will be the same within a couple percentage points, assuming it's not totally mismatched (like a 690 or 7990 in an 4x pci-e 1.1), and since you mention "budget" graphics, I see no problem.

To recommend any card, we need to know what you "budget" is, and your system specs, primarily Power Supply (make and model) and CPU

Obviously we're not talking dollars here, so I can't comment. But the 7750 is a great low power card, not needing any extra power than the slot you stick it in, and thus the safest bet without knowing more about your power supply.
