If you go to the above link and scoot toward the bottom, on the left side you will see a list of games and the FPS/Setting.
Max pain 3: High = 10 FPS, Med = 37 FPS and Low = 40 FPS
Battlefield 3, Only playable on low
Crysis 3, They only listed Crysis 2 which was 29 FPS for High and 40 FPS for Med
I think 3 is more demanding than 2.
