Sandy Bridge graphic performance maybe satisfactory when speaking of 13 inch level graphic card, and outstanding when it comes to integrated graphics, it is no where near any discrete graphic card currently out there in the market, and it's performance is unacceptable for a 15 inch "pro" laptop, you can see relatively lame bench marks here :

my only question is: what could apple lodge in the next generation of macbook pros, i'm talking 15 inch here since it's what i'm planing to get, now seeing how much gaming we're seeing lately, and by the fact that apple has been sliding in better cards in the last couple of years, i'd say maybe a 460m or a amd counterpart, being in my opinion the amd a better choice, which hasn't really been plagued by bad drivers, and by the pure fact that amd watt/performance is higher than nvidia by a significantly large amount, providing a longer battery life and less heat produced.
Anyone made a list yet? , i am in no position to give possible graphic cards due to the fact i am oblivious to the current market.
