Get a PC. Much better Gaming Device to Invest in.
Very costly for me if i go for a high end system, if i go mid range i'm afraid i may've to upgrade all over again after three years :( Consoles i can enjoy for minimum 7 years without any fear of upgrades. I can't afford a High end PC :)
Don't listen to these PC guys. There's things good about gaming on a console.
I game on a PS4. I recommend it highly.
