I have a radon r7 360 and a fx6300 and I was looking around for an upgrade. I was looking at the Rx 580 but had one worry in mind if I got it. Would having the old fx6300 bottleneck the gpu and not perform the way I want it to and the way it should. Also if you have any other gpu in mind that i should get instead please let me know. Ps i don't really know much about computers.
