EDIT: DAMMIT I DON'T WANNA SPEND OVER A THOUSAND BUCKS ON A GAMING PC....!!!!!
It's not that expensive if you build one yourself, and even if you get someone to build one for you and it is, you more than make up for it over the years with steam and gog.com sales. PC game prices usually drop faster than on consoles even without the insane 50% - 75% sales steam commonly has. Take in with this that PC gaming gives you access to free servers, free fan made mods/expansions/enhancements, more indie games, more F2P options (if you're into that), and a back catalog of thousands of games to choose from if you don't mind tinkering with compatibility settings or just use GoG.
In ye olden days consoles were less advanced but more user friendly, now they're just proprietary PCs complete with bad DRM, codes, updates, on-disc "DLC", patches and hidden fees. It used to be when you bought a game on disc for a console you knew you were getting a complete game, but no longer, so what's the point?
I wouldn't build a new gaming rig right now, don't get my wrong. Wait and see what the specs are for the new consoles and then build one at those specs or higher, and you'll be set for the entire generation since most A-list games are console-centric and indie games are typically less demanding.
