I'm pleased with the 2 vram because in a lot of discussions about buying a 2G futureproof GPU a lot of people say 1G is enough. ( i always say 2 if you really wanne be futureproof )
Because all the new ones have 2G the game designers will use that and if you wanne play future games at max settings you'll need 2G i think.
On the high end ATI doesn't need to fallow Nvidia's bloated path of high power consumption but their mid range and low end offerings are to my interest with my shrinking budget.
