one of the great things about amd is they sell their processors openly so you can do what you want with them. you can buy dual or quad opterons and tyan or abit or asus tech will come out with a board to support them usually already having one at the release. but guys, look back at apple's sales charts. what are the big sellers, imac, huge (original) new imac, huge again, ibook, emac is climbing the charts, what you don't see on major sales is the powermac series, it's low on the list because it costs to much, the power book sells really well, but nobody is really complaining on that front. the powermac just isn't a top seller, doesn't get top prioity. companies spend 3 grand each for a top end mac, 3 months later, apple brings on something new makes their 3 grand look like crap, and the company is pissed at apple.
beyond all of this, why is nobody looking at history. you went from 400 to 500 and 550, thats 150mhz. next time, 550 to 667, and 733, that's 183hz jump, then you went from 733, to dual 800 and 867, not counting the dual because at the time only like 2 programs could even use the second processor and the os couldn't so, that's a 133 jump again. then from 867, to dual 1gigs, well, that's only a 133 again, jump, anybody seeing the connection here. why do you all think that apple is gonna jump 500 mhz, even 400mhz in clock speed when it never has before. i realize they need to, but given history, i'd say we look at 1ghz, 1.13, and 1.2, and that'd be wishful thinking cause really, at most i'd think it'd be, 1, 1.1, and 1.67, which would be apple's highest jump in speed.
the last thing is, and i know this is said alot, but, if you go back to a pc, you are still going to windows, and i'm sorry but no way in hell i'm going back full swing, i have a pc and it's fine, but compared to osx, and i'm running jaguar 6c87, i would never buy another pc, doesn't matter the speed, it'd still be windows, and sorry, but osx is so far beyond windows it doesn't matter to me anymore. a 1.2 with ddr ram would be a faster mac than anyone has ever seen, so why are you so sure you know exactly how it will perform and how well it will work. why did you even buy a mac to begin with if all you were conserned with was speed? i have always been able to build pcs that run faster than macs, always, for far cheaper too. but i like mac, that's why i use it, work play, who cares, it's what i like, why use something you hate just because it runs faster, and i put an emphisis on faster, but not better, nor as stable, or as easy.
