Alan is absolutely right, take a look at
http://www.aslab.com/contents/workstations/Marquis-C250S.html.
Aslab is selling the Marquis C250S with the Tyan Thunder 2500 board
(ServerWorks HE chipset) + linux preinstalled now in quantity.

I ordered one dual PIII system with the Tyan Thunder 2500 board last
week and will report my experiences as soon as possible.

One really bad point of these boards is that they need slot 1 PIII which
are becoming rare and rare. So blame on Intel which is not able to ship
really perfomant chipsets for their prozessors! The i820 and also the
i840 chipsets are also with Rambus RD800 modules not very well
performing. I've run the stream_d benchmark on an i840 system (1GByte
RD800, two PIII 800 MHz) with a vektor leght n of 9912111 and got a
mesured memory bandwith for triads of only 585 MBytes/s. I have checked
all Bios values and they seemed to be correct. So take a look at the
price of this system (~ 15000 US $) and compare this to the memory
bandwith of the old BX chipset (~ 400 MByte/s for triads).

For the people who are interested in the measurement in more detail:

The stream source was compiled with the Portland Group FORTRAN 77
compiler, using the following flags:

-fast -tp p6 -Mvect=sse -Mcache_align -Munroll -Minline

Mvect=sse tells the compiler to turn on the SSE feature if possible (not
used here, because stream_d uses double precision veriables!). I only
mention it to avoid questions in this direction etc. So this flag can
also be left out in this case and has no influence on the performance
numbers (I have tested this!).
