It depends how well the game can utilize the cores. Look down at the last three in this benchmark
, for instance.
If the games only uses one two cores it might become a bottleneck depending, FX 8350 is no exception, because the cores are not really but more a part of a core - one module which can be seen a "core" is made of two bulldozer cores that have two integer units but share a 256bit FPU. Steamroller will solve the "poor" (everyone has to decide where is poor or not) performance in single threaded application such as iTunes partly but not entirely. Older games usually use up two cores which can cause issues.SkyrimeDiablo 3Star Craft 2
The difference betwen them is a few fps but if you compare to an intel cpu the difference will vary much more.
Overclock the cpu and the bottleneck won't be to obvious, around 4GHz or more. When overclocking you want to disable the turbo function, function thermal that makes sure that the cpu says within its TDP
