LinuxQuestions.org - have i got a fair deal?

Yes, basically. Here's some quick stats I compiled for you to compare.
These are three PCs here, each running Slackware with a 2.4.x kernel,
all running KDE, one browser, one email client, one xterm at the time
of these tests. I did not minimize the glxgears frame for these tests.
Just issued "glxgears" in xterm. The P4 2.4 (paul) has 1GB DDR333;
the Athlon XP 1600+ (peter) has 256MB DDR333; the Athlon XP 2600+
(james) has 256MB DDR400. All running current Nvidia driver. The
kernel on paul and peter are recompiled and optimized, almost no
modules; the kernel on james is default 2.4.26 bare.i
