Could a PCI E 2.1 graphics card run on a PCI E 1.0?

Yes, but no where near as effectively, then again there aren't many PCI E 1.0 cards around so if that was your only choice, yes it would work.

for the full effects of the graphics card, you would need a new motherboard, make sure it is compatible with your current memory and cpu. If not then you'll end up having to totally overhaul your system with a brand new computer.

There's many issues with 1.0 slot running with 2.1 cards.
So if you have 1.0 slot on the motherboard then you'll better with 2.0 card.

Just tell us your full specs and budget, we will give you advises. :)

Yes it should work.....

The thing is, some early PCI-E 1.0 boards were not 100% PCI-E compliant and had issues. Of course, by now most of them have BIOS updates to address that, so you may want to check for BIOS updates for that particular issue. Other than that PCI-E 1.0 only has half the bandwidth of PCI-E 2.0, but that generally does not affect performance that much. With lower or midrange cards, the performance difference is generally nill, and only in higher end cards will it be measurable.
