Anyone used this? I want to know if it's safe for me to boost up my WoW performance with this.

I did when I had my X800, but I was only able to get a small overclock before getting screen artifacts. And given the cost of the card versus the relatively miniscule performance gain from the overclock, I decided to just remove ATIcellerator and use it at stock speeds rather than risk damaging the card.

I'm using ATIcellerator II (soft mods the core/memory clock - no flashing required).
I clock the core up 5.7% to 500MHz, which is the stock speed of a PC X800XT; the Mac cards are slightly underclocked for (presumably) thermal reasons. I've experienced no ill-effects.
