For those asking why I built the computer in the first place:
I originally bought the 970 during the Witcher 3/Batman promotion, built the computer around the deal, and I have since used it for many games. It's only recently that it's slowed to a halt, and with Pro coming out, I don't see a lot of use in its future.
And PC gaming is NOT cheaper for me; I get new games for 20% off using Prime, and I sell them back (something I can't do on PC) for around 30 to 40 bucks when I'm done. I can essentially play new games for 10 to 20 bucks using this method.
Also to reiterate, if I sell this PC I'm definitely getting a Chromebook or laptop, which will actually be more suitable for me due to potential classes in the future.
Edit: I'm selling my current PS4 and putting those funds toward the Pro. Selling the computer would be entirely separate.
