I built my PC a little over two years ago, and my PS3 eventually became a Netflix machine. Stuff obviously looks better, but I just really like how games run better on my PC. BF3, Dark Souls II, etc. became that much more enjoyable without having to worry about the game freezing or stuttering. I'll probably get a new video card and monitor within the next year.
As for the new consoles, I initially thought about getting one this year, but with so many games getting pushed back and my inevitable PC upgrades, I probably won't get one until late 2015 or even 2016.
