napalm is right. 512MB is not enough for some of today's games @ 1920X1200 and up and it is certainly will not be enough for tomorrows games i am not going to buy a brand new card and have it crap out performance wise in 2 months. 512mb is enough for 1280x1024 but anything more is seriously going to limit the cards usability down the road. i remember when people said 256mb was enough now it can't even take 1280x1024
