I own two machines:

1.
Dual PIII 933
2x 80 gig Maxtor 7200 prm 8meg cache
1024 megs ram
GeForce 4 MX 440 64M Card
Dual boot, Windows 2000 Pro, Red Hat 8

2.
PIV 2.0 Ghz
2x 120 gig Maxtor 7200 rpm 2meg cache
1.5 gigs ram PC133 ( I find this faster than DDR, less latency )
ATI Radeon 9700 Pro
Windows XP Professional

I like both machines. I love my single processor machine. It is that simple.

I use both machines for computer chess and I find that I gain a little with the
dual machine in that I can run tournaments on one computer. That's it.

Really I don't find much of a difference in playing strength between my two
machines. The PIV system is actually faster ( dual is 1866Mhz, single is 2000mhz
) in speed, as well as getting tasks completed faster.

Personally I don't really care if Chess Tiger ever comes out with a SMP capable
version. I would actually prefer the one processor version.

On a side note, Vincent claims that CT is a very buggy program, and that the
author is lazy. As a previous beta tester of Tiger, I can honestly say I found
only one bug, and that was a book bug. The GUI from Lokasoft is the best
interface out there, I like Winboard as a strong second. Chessbase interfaces
are way to buggy and I would prefer not to have them running on my machines.
Chess Partner combined with Chess Tiger is terrific. Probably the best match out
there in computerchess for functionality. Can anyone name one better? If you
don't remember that I was a beta tester, read here:

Vincent, how buggy was Tiger when you lost to it at the Dutch Champs? And how
many times did you lose? Probably doesn't matter as Christophe was so lazy, I
bet he was taking a nap while it was playing Diep.

As you can see above I do use Linux as well. It has a long way to go before it
totally replaces Windows as my home OS, but I imagine one day it eventually
will.
