Okay, i've had a thought.. If you are going to show him this thread maybe we should explain rather than just criticise rightly or wrongly.
First of, RAM. RAM doesn't make your PC faster/more responsive, SSD's do that. The major thing with RAMin gaming is the speed not the quantity. The faster the inofmration can be accessed the quicker it can be used..
I've been playing some pretty intensive games recently and my RAM usage doesn't exceed 3.5-4GB. The findings from this tech website also prove that 8GB is more than enough:

The only reason you'd need more RAM is for video editing or rendering. I was doing a render (for uni) on my PC and ran out of RAM at 8GB.. UInstead of 6-7 hours it took 24+.. But that was a highly detailed assembly, rendered A0... All my A3 renders were done within an hour.
SSD: While an SSD improves load times, i dont see the advantage of having it on an SSD, it hardly improves load times in game and doesn't make it look any better. Id personally get a small 120/250GB SSD and a 2TB Mech drive..
GPU, well there have been issues with the R( 290(X) and black screening but i feel that is rare and will be sorted soon. The value for money of these cards are insane though.. Its well worth looking at..
All in all.. The first spec you/he produced i could build a rig for £500-£700 LESS and run the same game at the same FPS as you and have it boot as quickly. .. I would still be able to do the same in 2 years time..
