Oh you are on the list
On column 42 :)
Let me know if you can't see it. Maybe something is wrong with the list.
1GB vram is not really good my friend.
Today on a 40 player map in BF3 i hit 2212gb of Vram with 4xMSAA.
You dont neccessarily have to get a 4GB card, but I would advise you to get at least 2GB of vram for better gameplay.
If you are going to go on the Ati side, the new generation GPUs have 3GB of Vram which is plenty.
