as far as gaming goes there is no noticeable difference as even the top spec games only use 4 cores at the moment and both have pretty much the same single core performance, get the 6350 its a pretty good mid range chip and very good price/performance chip its not anywhere near as good as a decent i5 setup but it should still run most games paired with a good GPU such as the GTX 970 or R9 390 on ultra at 60+fps
