Hi Jeff,
    Both the X800 and the X850 will convert to mac but I gather they are
very troublesome and the dvi port never works as far as I know. Worth a try
for the vga I suppose as they are very powerful 8x agp. Both cards have a
new kind of rom lock which protects 'parts' of the pc rom from being
overwritten - so any ordinary flash on a PC in dos results in a garbage bios
unless a new command line instruction (I can't remember it though) is used
during the flash. The best way to flash X800/X850 cards is apparently blind
in a mac with Panther (Panther will boot with an unconverted card in) using
vnc - or something like that - it's a while ago. Aquamac's site and forum is
the place to go for method - I just looked and it's still there....the Bliss
7800GS 512MB card is also featured - that IS a nice card!

    I think strangedogs forum is still limping along too......
