Witcher 2 with Ubersampling enabled?
this ^
witcher 2 on ultra settings with ubersampling is hands down the most demanding game.
quad 7970's/680's are needed to maintain 60 fps at all times.
i can run ultra settings with uber enabled on my dual 7970's but i get frequent dips into the 30's. since i never dip below 30, i just use a frame rate limiter to cap it at that fps and all is good. i find that 30 is perfectly fine for this game
