No. I will elaborate. If that is his price range and gaming is all he wants to do then why go through the trouble of building a rig, when you can buy a console. Unless, its this like for Dota, or some other PC specific game? Generally people in the 500-1000 range I say buy a PC over a console only because you can use it for REAL things as well, since it is a full computer. But, if it's just for gaming why bother. Especially since games are made for consoles and poorly optimized for PC.
I just got a nice rig, mainly for video editing. i7 5820, 2 gtx 980's , Asus rampage, 32 gigs ddr4, SSD, etc. It was a huge upgrade for Premiere, After Effects, and Avid...A huge jump, but for gaming, not so much. You only see the difference at higher resolutions then 1440p, which he isn't going to do anyway. When I output games directly to my 42inch tv in 1080p, there really isn't that much of a difference. Sure it has a better frame rate, some extra nice effects and lighting but certainly not a 3,600 price difference from my ps4. But, since my computer can put food on my table and game it is a great purchase. So again, if you are just gaming and can only afford that much get a ps4 or xone at 350.
I just feel once you are buying used video cards and etc you are asking for a head ache.
