not horrible, and if you ever upgrade you CPU a rx480 is a solid card.
I just bought an RX 480, switched from a HD 7950 3GB. Am still using my FX-6300. In BF1, BF4, and anything else GPU bound, your framerates will increase and so will smoothness. Games such as Rainbow Six Siege will improve A TON but you wont get much more FPS in games that are already using your CPU limits. Which will be most of them. FX-6300 is a pretty good CPU still but I would suggest upgrading either way. I have had to OC my FX-6300 a couple more MHZ to keep up with the RX. It's not too bad but it's not exactly as smooth as you would get when you bought a CPU that can keep up with the RX. It is leagues better than the FX-6300 CPU.}
