Will it bottleneck?
Absolutely not, it would be more than enough. Ivy i5 (and Sandy i5 too) won't bottleneck even two GTX 690s/HD 7990s, so you really shouldn't worry about it.
The only real difference between Sandy/Ivy i5 and i7, is in that i7s has higher stock frequencies and has "Hyper Threading" enabled (which i5s don't have).
Other than just that, there is not that much of a difference, and i5s will easily run monsters like GTX 690/HD 7990 without any problems at all.
