yep, that AMD CPU is the weakest link in your build, the GPU is a close 2nd
I disagree. The GPU by far is what is holding you back in gaming. The FX-4300, though old, is still a quad core running at 4GHz boost. This CPU is comparable to a pentium G4560. A good graphics card to pair with your FX-4300 would be a 1050ti. This will give you a significant boost in graphics power, while not really being bottlenecked by the CPU. Going any higher than a 1050ti will most likely be bottlenecked by the CPU.
Have to kind of agree there.

Watch Dogs 2 really kills GPUs. For 1080p or lower, if you get a GTX 1060 or RX 480/580, you'll be able to hit ~60FPS on Ultra or Very High settings; a GTX 1050Ti might need to be turned down to Medium.
Unfortunately, I haven't been able to find anything about how CPUs affect the performance. But it wouldn't be a bad idea to see if you can find an FX-8300 or FX-8370e CPU for that motherboard, at least to tide you over until you can get a newer build.
