Would upgrading my gtx 950 to a 1050/1060 be worth it

Solution
950 to 1050, not worth it... http://gpu.userbenchmark.com/Compare/Nvidia-GTX-950-vs-Nvidia-GTX-1050/3510vs3650

950 to 1060, definitely worth it... http://gpu.userbenchmark.com/Compare/Nvidia-GTX-950-vs-Nvidia-GTX-1060-6GB/3510vs3639

But note that the 6gb version of the card is quite powerful and your processor might bottleneck it in certain cpu demanding games... https://docs.google.com/spreadsheets/d/1Q7lIYRK5T0ABLvAkgbM_2jJGvbhlep27mR-eRcCy4FA/edit#gid=0

The 3gb version might be appropriate for you.
