Upgrade 2700k or GTX 670
These are the two hardware components i currently own and i was wondering which one i should upgrade and what upgrade should i get for the most fps increase. I was thinking about upgrading to a i7 4790 but will that even increase my fps much compared to a gpu upgrade? I play games like dayz and arma 3 and my fps is shaky in cities, 34 to 45 but in the forest its like 70. I have 16 g of memory and a weird hybrid hard drive. I ran some tests on passmark and it says my hard drive is slow. Could this be my where my fps is going?
