Even a high end FX is going to have trouble feeding the 1660 Ti. We're talking about a GPU with right around GTX 1070 performance... and the most powerful card I'd put with something like an FX 8350 is a GTX 1060 6GB. You get a performance gain with a GTX 1070, but in many games you don't get the full capability of the GPU because the CPU isn't powerful enough to drive it.
Not to mention that a budget AM4 CPU like the 2200G is more powerful than the top end FX chips... and the most powerful GPU I'd pair with the 2200G is the GTX 1060, you're probably better off with a full platform upgrade.
