really depends on game.

in :
- anno 1701
- oblivion
- dirt
- prey
- crysis (!)
and lost planet

fps drop when activating 4xAA is much bigger with 8800gt then with 3870.


The worse cumulated results come from really BIG problems in "stalker" or "jericho" for example, where 3870 breaks down by a huge amount.

If you take out this games, where obviously driver bugs are the issue, then 3870 performs at least equal to 8800gt with 4xAA.
