I don't think it's the clock speed.
The recommended cards (8600 for AMD chipsets, 9500 for Intel) have more 
shaders, than the lower level cards. The clock speeds are not that 
The latest/greatest ATI Firepro for gamers has 800 shader processors 
(and costs $1,500)!!  The hottest (in more ways than one) Nvidia Quadro 
FX3800 has 192. IIRC the 8600 and 9500 have 16 or 32!


         Please let me know if anything I say offends you.
          I may wish to offend you again in the future.
