Hi peeps.
Few days ago i bought new graphic card readon r9 280, and what i went up is that my current CPU Athlon 4x 740 does bottleneck it pretty much (on most demanding games cpu usage is 100% when GPU is sitting there on ~70% usage.)
So as since im on tight budget after getting new GPU i decided to change CPU to another athlon, so i dont have to change MOBO ( Gigabyte GA-F2A88XM-DS2) becouse that will cost quite alot.
At this point i cant decide what to take, athlon 4x 760k or 860k, couse thats best of FM2/FM2+ procesors, and they cost just the same.
Whats your thoughts on this? What will perfor better?
Either way i gonna OC either 760k or 860k to around 4,5ghz. And that should make a end to the bottleneck.

Specs at the moment:
CPU: athlon 4x 740
GPU: Gigabyte R9 290 3x windforce
Hdd: 500gb 64 bit toshiba
SSD: 60 gb kingston
RAM: 8GB 1600mhz hyperx fury
PSU: 650w fsp Raider 80+ silver rated

That's true; even the dual core pentium anniversary edition out performs the athlon 860k even when both are overclocked to the max. Put that into perspective. It would be alot better to save then upgrade, both to a new motherboard and cpu. Go for an 1150 or AM3+ motherboard (with overclockability) and then go for either the i5-4670k (LGA 1150) or the FX-8320 (AM3+) Don't go for an 8350 instead use the money for a better motherboard as an 8320 is simply an underclocked 8350.
 
Going APU is going to mean you going to bottle-neck all higher-end GPUs. The best upgrade from your options is the 860K it will improve some but it will still bottle-neck that GPU. It would have been better to have gone AM3+ and popped a FX-6300 CPU in there. THE APU models you listed are for entry level gaming at best.
