I recently purchased an oem radeon 8500 card. the part number is 1028570700 (ie: not "1100 "1200 (LE) or "1500 (LELE)) which i think means my card isn't manufactured by ATI and also makes it a ***** to find out what the GPU clock speed might be. In advanced display properties the chip is listed as "Radeon 8500 (QL) Rev 0" How do I tell what clock speed I'm running at?
