Should I upgrade from a i5-4460, 16gb, 1600mhz ram, gtx 1070, 1tb hard drive, 500w bronze evga power supply to a new i7-7700k, gtx 1080, 750 gold modular, 16gb ddr4 3200mhz ram. I can sell the old one for $800 and it will take 1500$ to buy the new one so I'll have to spend an additional 700$. What do you guys think? Worth it or no?
