PIII 550 or Athlon 950?

[Derek Sivers <list@hitmedia.com>]

Almost off-topic hardware question, but I AM asking because of 
OpenBSD-specific issues.

I'm about to buy a server from Sera Systems.   A 1U rack space PIII 550 
server with 128k RAM goes for $1400.
They install and optimize OpenBSD (yay!) for your needs, all included in 
that price.

But - I need to buy FOUR rackspace servers, and at that price, maybe I'd be 
better off building them (cost: about $900 each) with an AMD Athlon 950.

I'd save $2000.  I'd have an Athlon 950 instead of a PIII 550.  And I could 
ask an expert OpenBSD person to advice/help optimize the original setup.

Does OpenBSD work better with PIII 550 than Athlon 950?   Would there be a 
big performance difference?

What would YOU choose?
(if you don't mind taking 1 wee second to reply...)

#1 - A PIII 550 server setup by a pro, for $1400
#2 - An Athlon 950 server, built yourself, with expert installation advice, 
for $900.


Sorry if this is too off-topic.
If it was Linux, I'd know the answer.
I'm just not sure if OpenBSD works better with one than the other.


Thanks!
