content: I had a $240 i5-4670K at the time (bought it to review some motherboard I got for free) and it was alright. Wanted to get into some GPU PCI passthrough stuff, and to my surprise, K models from Intel lack VT-d for whatever reason. Temperatures were also somewhat high with barely any overclocking (was at 1.2V @ 4GHz and could easily hit 80-90C; reseated the Hyper 212 Plus heatsink and tried different pastes along with heatsinks a few times to no avail). From my understanding, this is due to the cheap process Intel uses to attach the IHS to the die (plain thermal paste + large gap due to glue; delidding apparently fixes this). Ended up selling the CPU and mobo and got a 8350 ($170) + 990FX board ($120). Performance wasn't noticeably different at all, but I had AMD's VT-d equivalent, better multithreading capabilities, and had sane temperatures (get around 50C at 1.4V, same heatsink). So in-short, I went from a i5-4670K to a FX-8350. The latter cost less, offered the same performance real-world (in my usage), overclocked better, had better temperatures, and had more functionality.
