On April 11 AMD will release 4 new CPU's, Ryzen 5.
For the price of 189$ you can get Ryzen 5 1500x that have 4 cores/8 threads what is same as i7 or for 169$ R5 1400 with same 4c/8T.
That should give you same productivity performance of i7 for the price of i5.
So if you can wait i suggest you to wait until then and buy one of those. You will get much more performance for same or less money.
