I went to Low End Mac to compare my results with yours -- and discovered that although I have a Q840av in my bedroom, I've never actually benchmarked it. A project for the next time I have a few spare hours.... The math results tell me that your 840av is running at the correct CPU speed, since it's virtually identical to the reference machine. There's about a 10% difference between the reference 840av and yours, which strikes me as odd, especially since you have 60ns RAM. There's evidently some difference in configuration between your machine and the reference one. And graphics results are even worse. Do you have Virtual Memory enabled? That could be slowing things down. Do you have Personal File Sharing enabled? That could be slowing things down. Or maybe you're using a whole different version of the Mac OS than was used on the reference system. Perhaps the other 840av was benchmarked with 7.5.x or 8.x, which might have improved graphics support. Pure conjecture, but a possibility. -- Dan Knight, president /"\ ASCII Ribbon Campaign Cobweb Publishing, Inc. \ / No HTML/RTF in email http://cobwebpublishing.com X No Word docs in email http://lowendmac.com / \ Respect Open Standards! <http://maccentral.macworld.com/news/9910/27.deb.shtml> -- Quadlist is sponsored by <http://lowendmac.com/> and...
