Your system is struggling due to the weak hardware, and adding the GTX 1050 Ti won't significantly improve performance.
If the CPU struggles to match the GPU's speed, then performance can be limited based on the game. That's a general idea. But you have a decent CPU for mid-range gaming and a capable GPU for the same level. It works reasonably well.
It varies by game, but in your situation the issue isn't too bad.
There will always be a slowdown. It's just how hardware works. Bottlenecks shift between games and configurations too. Don't stress about it. The CPU isn't the best, but it should function well.
The HD 7970 is a suitable option, though it runs a bit slower compared to the R9 290X. The R9 280X could be another viable choice, but it tends to be even slower than the 7970.
