ive used this then got a core i3 8100 and i like the core i3 way better an d i can say this even tho i have a core i7 8th gen now


Poor

8 days ago.

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

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For a relatively cheap, outdated CPU, it performs just fine.
