there will hardly be any noticeable perform rise(say about 0-2%)
Here is case with SLI of gtx 680 reviews regarding PCI Express 2.0 vs 3.0:

Nope, well, not really, the performance will not be very noticeable if at all. GPU's don't really use enough bandwidth to max out a PCIE 2.0 slot.
Just keep your current motherboard for the time being.
