good thing it supports hyperthreading because some new game slike far cry 4 wont start without 4 or more cores in the cpu... but they work with hyperthreading... don't get too good of a gpu for that cpu... its a mid range cpu, so get a mid range gpu... If you could return the i3 and get an amd 6 or 8 core that would be better...an amd 6 or 8 core fx beats and i3 and is cheaper...
I cannot agree w/ this cpu upgrade path you suggested. OP should not go AMD (amd 6 or 8 core + motherboard) to improve performance. This is by far the best cpu upgrade path:
