it is so flipping slow for gaming

Comment 

Decent performing CPU considering it's age, general computing tasks tend to run smoothly. CPU intensive games tend to suffer slightly, but overall a great foundation for a budget system. Would not recommend for newer builds however unless found at a low price as there are many more cost effective choices available.—Dec '20

Have used for years and runs really stable

Despite its age, still a cost effective processor when coupled with a right GPU


Good

1 month ago.

I like it because Im using this processor while being overclocked to 4.3Ghz. Using it on a Asus Gene Viii and cooling it with a cheap Corsair Water Cooler, it is really stable, cool (39° when its 100% under load) and cheap! Perfect for gaming! Using it with a Rx Vega 56 and its not a bottleneck while on this state.


Terrible

Runs games just fine to this day and doesn't really bottleneck my GTX 1070, wouldn't get it now since better alternatives exist

For a relatively cheap, outdated CPU, it performs just fine.

It is still a very good gaming processor, of course, faster than games in ryzów, I have a score of 98.6 and RAM 112-115 on it
