Agreed. More Ram is always better, When it comes to video cards especially. The new norm will soon be at least 2 GB. When i jumped from 1-2 GB i didn't notice a huge boost in FPS, but i noticed i could handle more additional features, ie: AA and maxed every detail
It allows more room to keep the card longer without the need to purchase a newer one.
3 GB would be overkill
2 is currently the sweet spot from a 6950 or higher.
The one to see go on sale is the 7950, That would be just excellent... If it dropped to 250 one day i would have no issue getting it.
Expect the 8870 to be awesome as well.
