Do you have the A10-5800k now and looking to add the 6670? Microstutter is a real issue with crossfire, and these hybrid crossfire setups appear to be worse based on how many times I have seen people complain about it.
WoW traditionally has been a CPU bottlenecked game. That means the A10-5800k's CPU capabilities may also be holding you back from the FPS you want.
If you do have the A10-5800k now, how is performance with everything set to low? If you still have poor performance, another GPU will not help.[/qu
No, I am planning a new build. My primary use will be to play WoW and maybe other MMOs. Any other gaming I will do on my XBox. I used to play WoW on an Asus G72-GX with a C2D and GeForce 260M. I was able to play on high/ultra at over 40FPS, but not at 2080P. My goal is to play WoW on ultra at 1080P. I want a quad core and Intel/NVidea isn't exactly in my budget. I think the be Bulldozer and Piled river build look promising and deliver the bang for buck value I am looking for.
