Terrible

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


Good

3 months ago.

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


Poor

1 month ago.

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


Average

For a relatively cheap, outdated CPU, it performs just fine.
