I sorta know that PCIx16 2.0 is equal in bandwidth to PCIx8 3.0 but im wondering since I have a 2.0 x16 slot will it affect a r7 260X performance?

PCI 3.0 is backwards compatible with PCI 2.0. The performance difference between a x16 3.0 lane, and a x16 2.0 lane is fairly minimal.

No, not at all. Even the highest end video cards don't use more than PCIe 2.0 x16 or PCIe 3.0 x8. That particular card wouldn't have a problem down to PCIe 2.0 x8. It might drop a little if you go as low as PCIe 1.1 x8.
