Hey guys I am undecided between the -Corsair CXM750 ATX/EPS , 750 W, And EVGA 750 W GQ Series ATX

They are both around the same price of 80£ on amazon, and that's the amount I would like to spend atm.
Corsair is 80 Bronze while the Evga is 80 Gold... but I wanted more expert opinions perhaps I am not seeing something.

Thank you for your opinion.
 
My Specs are:

PSU: Corsair CX600M

MootherBoard: Gigabyte Z97X - UD5H

GPU: AMD Radeon R9 200 Series

RAM: Dual DDR3 8gb (total)

CPU: Intel i5 4670K 3.40GHz Quad Core (Overclocked)

And I am just running an SSD of 250gb and a Hardisk of 1TB.

I get very staggering fps sometimes when I play, and lately with a latest radeon GPU update I even blue screen if I overclock my processor - I read around and it seems my power supply is just not enough.

Also was thinking of adding Ram ... and 600W just won't cut anymore.
 


Even over the Corsair CS750 Modular? It has 80 gold too, I've just found it on amazon for around the same price.
