BOTTLENECKING:
People seem to get really confused on this. Basically the amount of CPU vs GPU ratio varies a lot between games. You can pair a GTX1080Ti with that CPU and have a GPU bottleneck, or pair a GTX1050Ti with the same CPU and sometimes have a CPU bottleneck.
I would just concentrate on the BUDGET you have and the GAMES you want to play.
R5-1500X + GTX1050Ti is an excellent combination for medium/high gaming, especially if you carefully tweak the games. (it's similar to the i7-3770K + GTX680 rig I had for four years until 2016 and I played Crysis 3 etc on that at 1080p, 60FPS at HIGH settings).
If your budget doesn't allow a better GPU yet then simply adjust the game settings as needed for the best experience with the GTX650 though I'd hold off buying demanding games.
