Hi guys. I'm planning to build a budget gaming PC that will serve as well as music production workstation and for some light virtualization for educational purposes. I'm spending about 430$ (or 320€) on the CPU-GPU combo and that gets me to 2 main routes: go for the cheap Athlon x4 760k and spend the rest on a R9 280x, or go with the stronger i5 4570 and a R9 270x. Two questions: What combo should grant me better gaming performance? And, is the AMD route strong enough for my other concerns? Thank you in advance.
