Gaming Computer - Recommendations?

Mr Nay needs a new computer. He plays a lot of games on PC and online (World of Tanks, mostly), and he also watches a lot of videos.



What computer / specs would you recommend for a new PC*?



(Preferably no more than $1200.)





*Note, I said "PC" not "Mac". He's not a fan, so let's not go there.
