With my 3.2 ghz pentium 4, X800XT, 1600 by 1200 2xaa and 16xaf, 20 fps. 1600 by 1200 2xaa noaf 30 fps , 1600 by 1200 noaa/af 40 fps. Recommend a 6800gt? Nah, you could run lost coast at least at 1024 by 768 with 2-4xaa and 4-8af with all settings maxed. with a 6600gt. Or at least 1024 with all settings maxed. The only real reason it is an fps killer is because it has long viewing distances in most places. Other times you hit an "arena" which has like 10 buildings with amazing textures and a bunch of physics objects which make your fps go down.
