A10-5800 vs A8-6600 Gaming

I am building a primarily Gaming PC and The A8 Richland CPU does not work in the FM2 msi mobo I bought, due to msi's weird "you need to install a trinity to update your bio's or you can't use richland" set-up. I was thinking of going back and getting the A10 Trinity. Will I loose or gain anything in Gaming/Graphics?

i didnt find any a8-6600 information, i assume u mean a8-5600k

btw heres the specs from amd website


i coulndt find the exact specs of the gpu's of thoose apu both are good in my opinion and doesnt differ much and since its "K" version u can probably get soome nice overclock with a good case ventilation and cooling system :)
