Well, you lose a generation of Instructions Per Clock performance, but gain hyperthreading. So multicore performance will increase, but single core performance will go down.
For older games and single threaded tasks, this is bad. For newer games and software that can use many threads, it is good.
Like I said, if you can get an i7-3770 or the e3-1245 v2.
Or save your money for a while and then get the cheapest Ryzen chip, board, and memory you can find. If you take the risk of bidding component by component and going as low as possible and not bidding a second time, you might end up with quite bargain.
