Benchmarking the Benefits of PCI-E 3.0 [hardwarecanucks]
The results couldn’t be any clearer: the HD 7970 doesn’t benefit in any way from a PCI-E 3.0 link to the CPU. Granted, there were a few small increases (and decreases) here and there but these are a result of averaging out the results from multiple manual benchmark runs and fall well within our margin of error. So to the relief of gamers and reviewers alike (hey, we still love our X58 test systems!), a next generation PCI-E interface isn’t needed to get the most out of the Tahiti XT core.

But in my case, my motherboard provides true 2 x 16 via the NF200 chip.
