well it helps the console, but because of the
framebuffer driver you need for Xwindow does
not allow mode change. if you want a higher res
you need to boot into that. who can stand 800x600
anymore ? 

its why i suggest to the OP he needs a video card.
of course i also said one thing at a time. 

personally no, i haven't tried an upgrade in mine yet.
i have got this one for free and it is sitting while
i gradually accumulate spare parts and cash.

the main thing that worries me is that the memory
is slow. i tested it goes at 25MB/s. that is something
you cannot upgrade.

also there is some story out there that sonnet
upgrades take away power from pci cards ? if you 
want video and a hd controller and / or usb or faster

plus the 8500 is known as the puzzle box as far as
adding RAM, plus

the physical card of the old L2 external cache needs
removing when you install
g3 or g4 upgrades so i hear.
