This would do fine, if all he uses the computer for is business and occasional light gaming (everyone tries for the heck of it, sooner or later ). Get any less card and you won't save much money; get more card and the price goes up in a hurry. I've used one of these for almost two years, they're stable and reliable. Good all-around card, good bang for the buck.
