all this aside, the newer (2400/2600) AMD Athlons are running the thoroughbred die, which has huge advantages in the voltage and power output. eg: our newest dual 2400+ easily runs 10c cooler than the older 19/20/21 dual machines. The bartons are even better, despite the additional heat producing transistors in the L2 cache, they also have a much larger contact patch with the heatsink.
Matt ps. i dislike bottom posting as it means I have to scroll al the way down to read your comments....plus im weird and read conversations backwards ;-) ----- Original Message ----- From: "Stefan Huszics" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Wednesday, June 04, 2003 10:26 PM Subject: Re: [hlds_linux] Server Recommendations. > Michael Devogelaere wrote: > > >On Wed, Jun 04, 2003 at 09:11:41PM +1000, David Harrison wrote: > > > > > >>>The #1 hottest (litterally) CPU available in the marketsegment we are > >>>talking about is the Intel P4 3GHz with HT enabled.
