I would buy a PC instead, you get a lot more power (sometimes for less) if you can take the time to figure out what you need. I managed to get my computer for $750, and it is infinitely more powerful than an Xbox 1. Of course, if you build it yourself, then you could get a PC of equal power to the Xbox 1 for a lower price. PC exclusives (like EVERY 4X EVER), multi-platform games, and even mere console ports usually have better graphics coded into them than console games do. Why? Because you can change a PC, PC graphics can be as insane as developers want, because they know the people who will buy the game can upgrade to handle it at any time. Consoles, on the other hand, cannot be upgraded. That's really why you should get a PC, because you can always upgrade it at the pace of hardware development, instead of needing to wait years for the next console to come out. If you look at this image, you'll see what I mean:

While a console may be easier to set up, you'll get new games first, and will appear to be perfectly fine, after just a few years your console will be horribly outdated. Illustrating this idea as well is this picture, comparing GTA V scenes from PC and Xbox 360.

That's why I would choose a PC over any console, because they are capable of adapting. If you already have a PC, then upgrading it for gaming isn't that hard unless it's positively ancient. It really is as simple as inserting Tab A into Slot B, then downloading the right programs. While upgrading independently is theoretically possible with a console, I suspect it would require an expert. With a PC, anyone capable of lifting the part can do it. As well as all that, the PC has entire genres of games that are nigh impossible to play with a controller, like the 4X genre. In fact, I would say that games are easier to play on the PC because the controls make quite a lot of sense, but that's probably just because I've been playing on the PC ever since my family got one. I'm pretty used to keyboard and mouse. Most indie games are also PC exclusives, and if you don't play indie games, then you;re missing out on amazing things. Along with those indie games, a lot of great classics are PC exclusive. Sure, you need to run them in comparability mode or buy them off of GOG.com, but there are some genre-defining games there, mostly in things like 4X and RTS, because as I have mentioned before, controllers are atrocious for those kinds of games. 

In short, Consoles of all types are perfectly fine for short-term activities. If you want something that will last, go PC. If you really, [i]really[/i] want a Console, I would wait for SteamOS, because seriously, Steam discounts. In the end, it's all up to you, but I honestly think PC is your best choice. You can disregard that if you want, but I cannot see a logical reason to do so.
