I was wondering if I should upgrade my pc. I have an i-7 4770k, and 970, 16gb of ram, an Msi z97 gaming motherboard, 2tb of storage, cooler master aio, and a 750 watt power supply. I was thinking about upgrading to a 1070, or a 1080, but I dont know if I should just scrap my current pc and build a new one.
