tom clancy the division 2

i'm using i5 2400 now, but the cpu is bottlenecking my gpu (1050 ti) on the game i listed....even on lowest sett, the game fps is not far from ultra sett (or even the same) so i kinda wonder is it worth to upgrade the i5 to i7 3770/2600 ? cant upgrade to a new chipset like ryzen or skylake above...
