if you wanna buy a CPU go with fx 8320- 8350
in old or single threaded games yeah i5 4670k>fx 8350 currently and for moderately threaded games i5 4670=fx 8350, and in the near future fx 8350> i5 4670k, let's review these benchmarks here

in crysis 3, where i5 3570k hits 80% load, fx 8350 is at 60% load and yet sabotages both i5 3570k and i7 3770k, what will happen in Crysis 4!? fx 8350 reaches 80% CPU load, the i5 is easily out of resources, which will lead to laggy performance!! grab the fx 83--
