don't waste money on a processor. won't make any difference. I saw a gtx660 with a 5800 and it was too much card.
what resolution are you playing at? and what makes the APU need a discreet card to make the game better?
I play at 1920x1080 and im just getting sucky fps 25-30 i do play other games though Far cry 3 hit man absolution Metro 2033+lastlight skyrim COD blackops2 just to name a few i do want to play bio shock infinite tomb raider crysis3 and a few others i cant think of right now and i know for half thoughts games just the apu by itself wont cut it
wont the a10 bottleneck that though thats what im afraid of what kind of fps can i expect to see out of gw2 and the other games ive listed with that set up
