I currently own a very capable power supply and have 8 gb of ddr3 ram, my cpu is a i5-4590 and my gpu is a gtx 1070 armor 8g oc card. Will my cpu or ram bottleneck my gpu? (if so how much?)
Yea, your CPU will be fine. If you want to check compatibility, use PCPartPicker.com . That site is very helpful and trustworthy and is what i used to make sure everything worked for my new build. And if anything, your ram could probably be the first thing to upgrade, but not for a while since ddr3 ram will eventually get outdated and slow
