Depends on your situation, as some people prefer certain games, for me:
Instead of a gaming PC, i went with a Macbook Air 3 months ago because of the mobility to and from school.
Most PC elitists will laugh at me for going with a Mac, but because of my study i'm on exchange in japan for a year i wanted the slimmest laptop out there.
Now a PC will be outdated during that time, but i can bring my laptop everywhere and decided to dish out the extra money here for a PS4 and bring it back to the Netherlands which is easier to transport :)
This is perfectly fine as the only game i play on my Macbook Air is World of Warcraft and LoL, and these run perfectly fine on High, getting 50fps, and frankly i don't play anything besides PC exclusives on it, and the rest i play on Playstation 3/4.
You can do it the other way around like me, play pc only games on pc, and the rest on consoles.
And frankly, the last desktop i bought was about 12 years ago with an Pentium 4, everything after that was a laptop for school & mobility purposes.
