 I would be that the Athlon would work just fine with LDM/McIDAS/GEMPAK
as long as the OS support was there.  I know a lot of Solaris Intel folks
are using the single CPU Athlons with great success (not Unidata
stuff, just in general).

The PC side of our company is Dell only, so I'll have to see
about the Athlon.  Obviously this might be something we'd build
ourselves if we went that way.

Has anyone tried a 2 GHZ Pentium yet? I will be making a call sometime
the next few months whether or not to get a 2.0 GHZ P4 or a 1.3 GHZ
Athlon. I'll be using my machine as a web server and making thousands of
graphics every day. Will it matter? Will the AMD chip run WXP, Gempak,
McIDAS and other programs just fine? I used to be as hardcore about
as I am about Linux, but in the last year, that has been blown out the
window! Does the floating point improve with the P4 2 GHZ vs. 1.7 GHZ?
