Generally when you build a PC you want to match parts based on budget. You should be looking at a 4690K not a 70K, but no, a 750Ti is not a good match. You use 750Tis with Athlon X4s and other sub $100 stuff like that or maybe an i3 at the extreme high end. With an i5 you really want at least a GTX 960/R9 280 if not better.
No bottlenecks though.
