You can certainly damage the card with overclocking - whilst it may seem
to run ok under normal application use it may struggle with heavy gaming or
heavy 3d apps and eventually give up the ghost. If you're unhappy with the
performance my advice would be to get a better card like a 9800 which is
much more powerful - the pc version can be flashed with difficulty - or get
a mac with a higher rated slot - the Sawtooth has 2x agp - the Quicksilver
has 4x agp and the G5 has 8x agp - each doubling of the speed gives twice
the performance - and the 9200 agp will run at 8x in an 8x slot. Performance
wise the 9200 is not as fast as the 8500 or the 9000 Pro.....
Probably wise to check out the Rage in OSX before clocking up....
