I have had this pc for a while but I've been wanting to upgrade so I was wondering how much I would be able to get for it. These are my specs: Ryzen 7 1700x with GTX 1080 turbo oc. 128 GB SSD with 2 TB HDD. 650-watt PSU and 16 gb ddr4 ram. all inside a Cyberpower case. I would appreciate the help !
