Remember when consoles were a good alternative to PCs, because the hardware inside was more expensive and optimized than a similarly-priced PC? Yeah, that's not the case anymore. Plus, there are a ton of interesting PC games you'll miss out on.
Since you have a freaking GTX 970 in that Pro Tools of ya, why don't you just get a Steam Link and a controller? It's like a Chromecast but for gaming. No need to buy another pc, all you need is a controller that hooks up to your PC.
