Hi, so I'm planning to get a HD 7970 GHz Vapor-X 3GB from Sapphire and later on I would get a second HD 7970 Vapor-X so I can crossfire it. Will my i5 3570k bottleneck the gpu ?

No your i5 shouldn't bottleneck it. I'd get an i7 if I was using the 7970 though !
No it will not bottleneck and for gaming even with quad crossfire the performance will be the same i5 vs i7, just make sure you have enough space between the two cards, and have a quality psu with 850w.
