Well, one of the 512MB sticks I bought is defective, so I'll have to exchange it :/ But even 768MB of RAM makes a noticeable difference in OSX (and of course in OS9 it's pure gravy...who'da thunk that memory usage could go up 10x in just a few short years...) The visual effects are still major overkill for an 8MB Rage Mobility (the shadows don't seem to be a problem, but the scaling effects choke noticeably; I think Onyx can disable 'em, but I'd really rather just have animated window outlines as in OS9 ) but at least everything else is running better...
