I'm really just in it for the cheap games, and that's behind all my "build yourself a PC" suggestions. It's never been cheaper to slap together a decent system, it's way easier than it looks, and it totally pays for itself in the long run. Honestly, most games run just fine without having to tinker, although you will occasionally run into infuriating shit like it taking me a while to figure out Uplay was bogging down FC3 performance.
Besides, when that anti-used console game shit kicks in, you're basically gonna be playing on a closed PC with all of the drawbacks and none of the perks, so you might as well.
