Because A6 is crap... If you're gonna go AMD at all, go A8, A10 or FX
I call Bullshit on "Maximum Operating Temperature" I have had my a6 6400k running at 87-98 degrees C for about 10 months avg 7 hours each day now and i have not seen any degrading yet.
mada faka research before you comment, this intel pentium g3220 is a 4th gen haswell processor. thats why its fast and newer than the old amd a6 6400k.

mada faka this stincks, are you all stupid, how can a fuckin old pentium win a A6 AMD, You dumbass
