A lot of the time people think that a card with more video memory always is faster than a card with less but that is not a true and not a good way to pick cards.
Basically he needs to know what resolution he is going to game at(I assume he plays games), what games he'll mostly be playing, then look at reviews to see how well the main cards out today perform in those games at his native resolution. Which ever gives him his desired performance for the best price is generally the winner.
OR, if he doesn't mind dropping some serious cash he can just buy a 6950/6970 or gtx570/580.

I know where you are going with this but honestly raw specs are not a great way to pick a gpu. Otherwise the HD2900 would have been the best card ever, which as someone who owned one I can tell it certainly was not.
In the end only two metrics really matter for gamers, performance and price. Secondary considerations like noise, heat, power can matter for some form factors though.Edited by Mygaffer - 5/31/11 at 7:30pm
