Their nothing worth upgrading to other than a 6 year old 8350. If you can find a cheap used one it would help a little.
With the prices of video cards right now is not the time to buy a card.

Here's FX-8350,

Though, the gain in performance is too little for it to be worth spending money on it,

For gaming, you'd be much better off if you go with the new CPU-MoBo-RAM combo, e.g this one:

The problem is that you not only have a dead platform that has no "good" upgrades, your GPU is sub-par, particularly for those 2 games:

Limited to normal textures on GTA V, & you won't be able to use Ultra settings for Fallout 4.

Which means a GPU upgrade...which currently also means your budget is blown out of the water.
