New numbers are as follows; all shopping done in 5 minutes online at
www.netbuyer.com :) Note: Prices are in American, so figure there's a bit
of an exchange rate (presently 1 US dollar = 1.39 Canadian OR 1 Canadian
dollar = .72 US)

CPU		MHZ	COST	Speed		Ratio
K5		133	$75	320,000		4.27		
K5		166	$97	370,000		3.81
6x86 P166+	133	$62	279,000		4.5
6x86 P200+	150	$74	304,000		3.23
Pentium	133	133	$107	165,000		1.54
Pentium	200	200	$227	265,000		1.12
Pentium MMX	233	$349	305,000		0.87
K6		233	$315	360,000		1.14

Added Info
Intel PPro	200	$459	500,000		1.09		
Intel PPro(oc)	233	$459	585,000		1.27

One thing that people forget is that you haveta keep in mind that those
CPU's (non-intel) don't support SMP and some other things that Intel chips
do. Don't get me wrong; I KNOW the K6 233 is a frigging fast chip that
runs like a P200 and a a third of another, but what if you have a dual CPU
board? My Dual P200 is still running faster with 2 Intel chips than if I
had 2 AMD K6's, because they can only be run one at a time. Figure I'd
haveta buy a whole other system to USE that other CPU, and check the
kkeys/$ again. Go up to a system with a Quad PPro design or our Dual
PII-266 system (and then overclock them to 300 MHz, like the AMD and Cyrix
chips already are internally), and check the numbers again, especially
against having to buy 3 EXTRA whole boxes to run the cpu's in, and then
assume you want these to do SOMETHING besides RC5 someday where having 4
CPU's in one box is MUCH better than 1 cpu in 4 boxes.

It depends on your needs and what equipment you already have as to what
you should buy.
