Yeah that i7 should be able to handle it really well. I've seen test videos of the i7 in the 700s series for modern gaming and those were amazing for their age, you should be fine
i7s in the x700s are NOT THE SAME as the i7s in the 9xx range. The difference is that the 9xx range is the actual first generation of i7, named Nehalem, and the only ones in that generation that are 700s are i5s.

probably handle it well enough possibly. I have no guarantee it will run great, I actually had an i7 930 myself a while ago and upgraded to Haswell and the performance gain in anything that was CPU intensive was noticeable (which for the most part was any Total War battle with lots of units and city pathfinding, large city battles were essentially slideshows because the CPU struggled to keep up but still going 40+ FPS). As for anything else that wasn't super intensive on real time AI, it was decent at best.
Overclocking it properly will help greatly, my old EVGA X58 SLI LE mobo with that 930 CPU had a great "dummy OC" feature that just overclocked it automatically for you to 3.2 GHz and it ran great (but hot, they're on 45nm silicon which is a little less than 3 times as big as current silicon).
