Sell those 2 and buy this. It has a much weaker GPU but it's a well balanced system and it's about the best you can get for that money - new. You could of course get better value if you buy used, but for $200... I don't think it's doable.
Woops, I thought you said you got AMD 280X, but it's GTX 280. Then it's definitely not doable, sowwy. He'll need to stretch more.
