My current PC spec is similar than the laptop your friend intends to purchase. My wake up call for a new pc was the fact that I couldn't even run Assassin's creed black flag playably at 720p!
So no, not even close to mediocre gaming. If he must have a gaming laptop, have him find one that is at the very least based on AMD's A10 7850k. At least that one can run 1080p at medium settings.
And 4gigs of ram, not even closely enough.
