I agree the cache could be important, and if it is, then what you really
want is one of the P4C with the 512K cache, if that is important to your
application. Run it on a motherboard based on the Intel 865 chipset,
and you can get interleaved DDR400 (800 MHz FSB). Or you could get
a Barton cored Athlon XP (which also has a 512K cache) and an NVIDIA
nForce2 based motherboard and have roughly similar performance for a bit
less money. These are likely to be the fastest single processor
solutions - since this is off-topic to some degree I won't continue
on to dual processor solutions unless somebody really cares (dual
Xeon on SuperMicro motherboard is my recommendation).

Who is the vendor? New Egg has it for $100 and I have dealt with them
many times, as have many of my friends and co-workers - highly
recommended. Anyway, that XP2600 will have a 256K cache, for
$96 shipped you can get Barton cored XP2500 with 512K L2 cache
which might be a better choice where cache size is important.

As mentioned before, I highly recommend them. Always close to the
lowest price on Price Watch, and always good service. I have no
relationship with them other than as a very satisfied customer.

And if cache is important, the Barton core XP2500 or faster might be
a better choice.

I am currently using Gnome, but KDE was OK too when I used it a couple
