I was getting annoyed with my new iMac as they still do not allow you to shut up that annoying startup chime and believe me its louder than my last one ever was so i did a little searching and found this.
hxxp://www5e.biglobe.ne.jp/~arcana/StartupSound/BETA/index.en.html i broke the link i hope just incase admin dislike a direct link to this great find and i hope it has not already been posted.
I can also say that the top range imac with the upgraded video card they now do runs games or at least runs WoW at full power and in windowed mode as well without any lag or stalling and i guess any games with similar needs will be just as good with one , but i guess that only means something to mac lovers , but it was time that macs caught up with the PC brigade.
