Your problem is likely the dedicated video RAM...my card, despite only scoring 200, has 128MB of dedicated RAM.
2xAA is 2x AntiAliasing, minor antialiasing, but any antialiasing is hard on the video card because it smooths out all the rough edges on the graphics.
As for running in windows mode...I don't find Civ to be any more stable in this method(although others have, from what I read long ago before v1.52), I do find that it takes less time to bring up other apps like notepad or the CFC website though.
As for the 2000 I mentioned, I was referring back to the Radeon X1700 on the laptop I linked to for you...It scored a 23xx on the same test you looked at for the two Nvidia cards and has 512MB of dedicated RAM.
