Version/Build recommendations desired

[s harper]

This coming weekend I'm planning on building a dual
Athlon MP 
2000+ server with a Chaintech 7KDD AMD 762 Motherboard

w/onboard IDE RAID. On my "current" box I've been
running 4.X-
Stable, but it's a single cpu machine. It's primary
function 
will be an Apache web server.

I'm very interested in running 5.0 so that I can take 
advantage of the SMP enhancements, but I'm also
worried that 
it may not be very stable for my configuration.

Assuming that those on this list have a lot more
experience 
running FreeBSD with multiple CPUs, what are your 
recommendations?

Specifically, should I stick with 4.X, or start using 
5.0? Are there widespread problems with 5.0, or do I
have a 
pretty good chance of having a stable system? Which
build would you suggest?

It's not mission critical in the sense that I can't
build it, 
then rebuild it if it turns out to not work out well,
but 
that's obviously a lot of work and wasted time that
could be 
avoided if I can get a warning that there is little
chance 
5.0 is stable enough to run on my configuration.

Also, if you have a recommendation for one or the
other, are 
there specific kernel/tuning parameters to make sure I

include or to make sure I avoid like the plague?

Thanks in advance for the benefit of your experience
and 
advice,

Thomas
