cpu USAGE 100% IN ALL GAMES AND HUGE FPS DROP, bottlenecking by all the graphic cards, TRUST ME : DON'T BUY THIS CPU


Good

Better for average mid end budget , cause of low watt consumption, cheap price and compatible my GTX 1060 3Gb without bottlenecking


Good

It's great for low end gaming, but once you start playing the higher end games, it starts failing.


Average

14 months ago.

For a relatively cheap, outdated CPU, it performs just fine.
