PCIe 2.0 vs 3.0

[deadsite22]

I have a motherboard with PCIe 2.0 and i'm looking to buy a PCIe 3.0 graphics card, the MSI R9 270. Is there a big gap in performance between the two?

You will be perfectly fine. That card cant even fully saturate a PCI-E 2.0 slot.

Not much big gap. None if any at all. The difference would be significant in benchmarks if you use quad or tri SLI/Xfire. But for single or dual GPU setups, doesn't matter bro.

pci-e 3.0 cards work in pci-e 2.0 slots . When you have one or two cards , the performance difference would be negligible - pci-e 2 vs pci-e 3
