Should I get a gaming PC, X-box or PS4?

So, I've wanted a gaming pc for a while now, and I was recently told by my father that we could each pay half on one if I improved my grades.

I've known a friend since I was 6 years old, (currently 14) and we play games together, (Minecraft, CS: GO, League of legends, etc.) as we're growing away from pc games, we were talking about me getting a PS4, as he has one and plays Black Ops 3, and GTA5 on his PS4.

However I've also been talking to my mates at school about getting an x-box 1, as they all have one, and all play GTA, BO3 etc. I'm not sure what to do, and what console I should get… I have enough money for either of the consoles.

Thanks for your help,
Kind regards, Reegan.

Added (1). Update: I know you can't play games with people on different consoles, so i'm not sure which one I should get. The games i'll be playing are:
- Assassins Creed: Origins
- Call of duty: Black ops 3
- GTA: V
- Call of duty: World war 2

Which games do you want to play? Specifically, what EXCLUSIVE games do you want to play?

For instance, if you want to play Halo you need a Xbox but if you want to play Uncharted you need a Playstation.

Make a list of the games you want to play for each console. Only consider exclusive titles. Things like CSGO for instance, are playable on both but you can only play with people who have the same console as you so that might be another factor.

Anyways, the console with the longest list, is the one you should buy.

If you like first person shooters then 100% gaming pc! If you like to sit back relax and play a game then console. It's like a whole new experience using a mouse and keyboard playing something like BF4 or BF1.

Gaming pc don't only play pc games. They can also play console games that came out for pc.
