I got the same values with AGP 2x, then I switched to 4x (in the BIOS):

Blit                                   3.01 secs (  272.34 MPixel/sec)
Blit colorkeyed                        3.01 secs (  272.34 MPixel/sec)
Blit with format conversion            3.05 secs (  120.45 MPixel/sec)
Blit from 32bit (alphachannel blend)   3.06 secs (  120.01 MPixel/sec)
Stretch Blit                           3.04 secs (  164.07 MPixel/sec)
Stretch Blit colorkeyed                3.04 secs (  164.07 MPixel/sec)

Running in 1024x768x16 on a G550,
does anyone know if this is the normal performance for AGP 4x?
