First, thanks very much. I'm glad it has been somewhat useful. actually awhile back after I made this post refraction stickied his own guide that was a little less in depth than mine - more of a summary. It was unstickied it for some reason (probably too many stickies in this forum) - but my intent was to help people see that if they had a particular processor (3 GHz Pentium 4 is classic example) they wouldn't get good speeds, even though the PS2 is only 300 MHz. So they wouldn't ask questions regarding slow speeds on an Athlon XP.
Again, thanks for the comment.
