Should I buy a next-gen console even though I have a pc desktop?

So I've bought a pc and I'm happy with it but I'm wondering if I should spend my extra money on a next gen console. I was thinking of saving it for an iPhone but the second thoughts are happening again.

Well if your pc is a powerhouse and can run games at a good fps and will be able to for the next couple of years then no don't but if your pc is an average gaming pc then yes get a next gen console the good thing about consoles is that they can play any of the current and future games with no upgrades and no problems and if you do get a next gen get what your friends are getting if you play more solo but want a better/ higher quality games get a ps4 better graphics and fps and if you want a variaty of games with a little lower quality but more features get an xbox one cause you get a lot more with xbox's gold rewards thing than playstation plus but in the end the ultimate descision is your good luck and happy gaming
