well, will you guys argue over this forever?
of course if an application can take advantage of all 8 cores the FX does crush the core i5 just look here in tom's the 2013 cpu testing you will realise pretty quickly that in every multhi-threaded workloads the FX is quite a bit faster than the core i5...the same results will apply to games as well, when games start using those core a lot more the core i5 will once again be defeated in any workloads that will use 6 heavy threads or more, that's it!

So to those who stated that
''Only an extreme few make use of multiple cores'' we can clearly see that this is not true...as of today most applications do make good use of multi-core chips, the only area where it's not yet the case if for games but this is all about to change...
Here's total score (time) for all the 30 tests:

So yes the FX chip is one hell of a performer that does indeed better than a core i5 in most situations except in single-threaded games and applications...wich are slowly fading away and are becoming more and more a thing of the past everyday. Intel does have a better performance per core than the competition but it's no longer all about IPC nowadays...this should conclude this argument...forever.
JOOK-D :
I've yet to really see an instance where an 8 core FX can "crush" a 4 core i5.
So you are loosing your time around here everyday trying to sell intel chips to everybody but you never actualy checked the benchmarks provided by tom's hardware experts?
