unfortunately , no
your g5 for example - won't run anything new on the mac , ie; radeon x1900 or nvidia 8800
it's a very sad state of affairs , but basically when you buy a tower from apple - you're stuck with the video options at that time..and there are NO upgrade options available to the user - apart from buy a NEW tower - which is quite frankly absurd
tbh - i'm really very angry and even depressed aboot this whole thing , i even emailed john c dvorak to see if i can stir a hornets nest over it
if there's no resolution on the matter - then i'm finished with apple , no bs , spent over £4k in july on something that is basically going to be a very expensive doorstop in a years time..

the word from apple - at least i don't have a G5 - that would REALLY annoy me !

the G5 quad is still a very powerful computer - crippling it this way is simply obscene
i'm making a big deal as the gpu in leopard is more important than ever and the x1900 which is the current top of the line option is a noisy , buggy , overheating pile of garbage
