Anymore if you build your own gaming computer you are a fucking idiot. The cost is astronomical however if you find a good deal on a great computer you can have a better value than a gaming console.
That being said, there are a ton of games that don't come out for the computer and even when they do they are a year or more late to the party. So if you are a true gamer who needs to play everything as it comes out then buy a console if you can wait a year or do without a lot of different games buy a gaming PC>
