well the r3 will perform within 10% of the i5 in most titles, and it will run you 100 less, you can get a good B series MB which you can overclock with for about 50-70 less then a good overclocking board for that i5... they aren't really in the same price class, so its your choice really. If you have a 1080p / 60hz monitor, I doubt you'll see much difference. Overall the i5 will perform better if overclocked, but again you won't notice on a 60hz monitor.
