Both 5870 and 480 unable to handle Starcraft II official campaign at 30 fps

@sniper_sung: What is your point?
Everybody who ever played RTS has experienced slowdowns when larger groups of enemies fight - so nothing special here.
Is "lower than 20 fps" too slow? Then watch these graphs (scroll down the german text). It shows the cpu scaling of SC2 with a GTX480 graphics card (@1024x768 resolution without AA/AF to minimize gpu impact). There are a lot of sub 20 fps grey "minimum fps" bars - so nothing special here, either.
