it depends on the use! i5 is the best gaming option for the money.i7 has 4more threads and 2mb more cache memory which has a greater impact on multitasking operations, picture-video editing but less impact on gaming.(there are games though, that take advantage of the extra resourses, multiplayer ones mostly.!) ,still an o/ced i5 results on a better performance than a stock i7! so with less money can have better performance! finally as a gamer i5 is good and an o/ced even better, if you also do other demanding stuff while playing, or running professional aplications, i7 is your choise!
