I am currently using a Gtx 260 in my pre-built system from HP (I just didn't have the funds to build from scratch at the time). The motherboard in the PC only supports PCI-E x16, as compared to PCI-E 2.0. I am wondering whether or not my gaming performance would be affected by upgrading to a motherboard supporting PCI-E 2.0 and in what ways.

Nope, you will see no difference between a PCIe 1.x and PCIe 2.0 motherboard.
Current generation GPU's (with the possible exception of the GTX 295) are unable to fully saturate the bandwidth of a 16x PCIe 1.x slot.
Therefor, doubling the bandwidth will show no performance gains.

I do not think that you would really notice the difference ,,I am running my video on pci-e 2 and I do not really notice any diff,I do not think that the games can really take advantage of the bandwidth right now,who knows in six months or so tho,,,,,.:)

From my experience there was almost no difference between Gigabyte g31m s2l (pcie-x 1.0) and Asus p5ql (pcie-x 2.0).
I tried 3D mark Vantage and first one did P12730, second P12814. That is less than 0,7%.
