the i3 3250 will bottleneck the gtx 760/660 ti?

[Guest]

will need a better processor? if yes an i5 3330 will be enough?

No, it will not bottleneck a 660Ti/760. I have a backup m-ITX build that had an i3 2120 with a GTX 660 Ti, which now has an i5 3470, and the only games that I've seen even modest performance increases in are those that tend to be CPU limited on any system.
