I have the 2.33Ghz, 7600GT, and 2 gigs of RAM. I loaded XP last night, which was incredibly easy with Boot camp. Oblivion installed with no issues. It detected High Graphics and autoset the graphics levels. The game played flawlessly. Even the outside areas were smooth. I only had time to get out of the first dungeon and run around outside a bit but I assume my MAC will handle this game fine. Over all I am extremely pleased with my first MAC purchase. Everything seems to be so darn easy on a MAC.
