Save your money and go with the i5 AND the GTX 960. It's not that much more than the 750 TI anyhow. If that's not an option, I'd play for the i3 with the 960 unless you're gaming CPU intensive titles then the i5 is a better choice. What titles you're intending to play makes a big difference in component selection. You'd be a lot happier if you waited until you could afford both the i5 and the 960.
