My PC is a mid range pc and I can play arma 3, stream it, and record it at 20k bitrate, all at the same time with no problem. When I do this I get about 60fps playing. I will list my specs below, but you already have a way better CPU than me,and are probably looking at a way better graphics card. Anything you combine with that processor should be great. I have always been a die hard AMD fan as well. Still have the graphics card, but went with a intel processor, when I bought mine, and I love it. I still have love for the AMD cards. Like I said, my pc is just a mid range build, not too expensive but gets the job done, and it can do anything I want it to. Nice build bud.
