I've had my gaming laptop 5years now, it's running 8800m gtx in sli, and despite only having a dual core 2.6ghz processor as well it's still able to plough through new titles on medium settings at 1366 x 768.
I'd upgrade but can't justify the cost of a new gaming laptop, makes my eyes water!
5 year old laptop with dual 8800m mustve been a very expensive and powerful gaming laptop back in its day, one of the first proper gaming laptops.
I made a XPS with a single 5650M last me three years before I decided it was time to buy a new gaming laptop...
He will find loads of games to play with an 8800GTX, they were one heck of a card back in the day, many still use them.
