[ale] motherboard recommendations?

[Tucker Balch]

Hi,

We're going to upgrade our Linux box from a 486DX-50 to a Pentium.
Motherboard lingo has changed a lot since I last bought one, I 
was hoping some of you could help me out.  THanks in advance!
So here are the questions:

	Prices seem to depend heavily on the chipset in use, for
	instance, an otherwise identical motherboard costs $70
	more with the Triton II chipset vs the Triton chipset.
	What's the difference and is it worth it?

	We can get a dual-pentium board based on the Triton II
	for only $40 more than the similar single-pentium version
	(not counting the price of the CPUs).  Will the dual board
	with one CPU run as fast as a single-CPU board?  I'm
	looking specifically at the Tyan Tomcat I ($239) and
	the Tomcat II ($270).

	Are Tyan boards any good?

	What's the deal with the Cyrix vs Intel CPU speeds? e.g.
	the ads imply that the Cyrix 100 == Intel 120. Why didn't
	Cyrix number theirs the same?

THanks!
