user1106: I'm using guiminer with flags -v -f30 -w128 under windows 7 but all i get is 120Mhash/s thats like 75% of what the table shows. Any idea why is that?

user1107: If you are using ATI Drivers 11.12 or 12.0 or above you need to set the worksize to 64.
Also the new drivers are a bit slower then pre 11.12 drivers.
