PCIe 3.0 GPU on PCIe 2.0 Motherboard ? Please help

[Fairlightbb]

Next munth is my birthday ! So i will upgrade my current GPU (Asus GT 640 4gb)
to a ASUS-STRIX-GTX750TI-OC-2GD5.
But my problem is that my current motherboard is ASUS H81M-A, which only supports this expansions slots,
1 x PCIe x16
2 x PCIe 2.0 x1
and the GTX 750 ti requires PCIe 3.0. Will i be able to use it on the current slots that i have, or i will have to buy a new motherboard ?
If i can will i lose any perfomance ?
Thank you !

The GTX 750Ti will still work in a PCIE 2.0 slot but will just run at pcie 2.0 speed, not that it matters since the difference in performance is negligible.

what is the diffrence in perfomance like % ? 10-20 % ?

It's negligible. It could be 0.01 fps difference, or 1 fps.

The difference in Frame rate can depend on what generation card you have. The older cards like the 750, 660 etc will only have like a 5-10% difference in performance running on a lower PCIE Type, however in the newer generation cards like the gtx 1060 the difference in performance is noticeable different. Its more like an extra 20-30FPS in most games.
