That helps alleviate some of the confusion.

Its hard to tell when leasing a co-located server :) The monkeys at the
data centers only go by model #.

Only when hunting for a deal on E-bay or Froogle. Listings typically go
by model #, you have to weed through the listing or do some more digging
to get the spec sheet letting you know what socket your getting, plus
the above mentioned problem when ordering them on a monthly lease
co-located.

Since the HP's I ran into are so common and popular, I thought I'd
mention it.

And that's exactly what AMD delivers.. was never in question. My point
in posting was to (hopefully) stop someone from making a 5 - 6 thousand
dollar mistake when buying :) The bad part about great deals on sites
like E-Bay is all sales are final. 

When shopping from a list like this :

If not already familiar with AMD, Its an easy mistake to make.

Exactly. I wasn't criticizing :) Apologies if what I posted was
misinterpreted. Its a non issue for most newer systems anyway.

AMD would need to work hard to lose market share. The performance /
price makes it a no-brainer.

Combined with virtualization technology, in developing countries with
inadequate or antiquated power grids (such as here in Manila) its even
more of a no-brainer. 

I wasn't suggesting it be changed, only posting a look out :)
