Your ISP cannot provide the speeds.
Allow the lad to wait 18 months and THEN look to the new Intel 3D
In the in between time - save 300 a month to purchase the new system....he will become the fastest gamer on the block.
for the next 18 months.
(On the other hand - purchase him a musical instrument - and let him be frustrated - BUT HAPPY - for the rest of his life.)
Sincerely,
