It looks like two that should be considered are the
Asus P5AD2 and the P5GD2.?
Anyone have any comments on these two? I need quick machines and
stability. The reason I asked the question here is usually the people
that frequent this group know about any boards that may not be stable.
Thanks for any advice or comments
It depends on how you define "hot"
http://www6.tomshardware.com/motherboard/20040810/index.html
You can either get good performance using an existing DDR based
board, or go with a 3.4 or 3.6GHz Prescott LGA775, and get "hot".
The way things are going, a high end Intel solution will be running
in thermal throttle mode all the time, unless maybe there are
some good water block or other exotic cooling solutions. AFAIK
water blocks for LGA775 are not available yet, and neither are
third party HSF combinations. The motherboards themselves are
shipping again, as one poster was asking about a thermal problem
with a LGA775 a few days ago.
For LGA775, it is too early to make comments about stability yet.
There aren't enough boards in the field, to make any comments.
On the desktop front, one advantage of DDR2, is that a new
generation of memory chips is being used that allow roughly
double the memory density. This means 1GB modules are more
common in this tech, than in DDR. And the memory runs cooler,
due to the use of 1.8V instead of 2.5+ volts.
The CAD applications I've used were all single processor type
applications, so a dual or more processor board wouldn't help.
(If you are running simulation or crunch-style apps, then it
can help.) Maybe your CAD applications are different. You
could shop for a dual Xeon or a quad Opteron, if you have the
budget. Apparently,there are Xeon processors now with FSB800,
and the NCCH-DL can run them. (For Opteron, Tyan has a selection
of Opteron multiple processor boards.)

If you do decide to go with a 3.4 or 3.6GHz LGA775 processor,
try to do as much reading as you can, on finding decent cooling
solutions for them. Buying a computer that overheats your disk
drives, and runs in thermal throttle mode all the time, isn't
the answer.
