Can't mine ETH.. It makes my computer laggy as f*ck. When writing letters come to screen after 2 secs, and mouse pointer is lagging too. Can't really do anything when mining eth.

GPU mining is really a thing of past I would not invest much time as so many are pump/dump. If you already have gear... eth is going to be best option. But again I don't suggest GPU mining for most.
Buying new GPU's is expensive... and turning a profit is not easy like it was years ago where 3 month ROI's were almost guaranteed. Also I would not mine on a PC your using as you mention lag. Dedicated mining machine is more practical, due to high intensity needed in most cases.
