I have build three 4-core presentation workstations; this is the most
responsive-fast computer what can be built today with best ratio
(performance*reliability) / (price*noise).
The total cost = $2463 + (tax if applicable)
The correspondent hardware configuration and some tips can be found
below:

//---------------- Tips
If BIOS <7.0 the bios has to be updated to v7.0. (FD is required)
Old BIOS can support one dual core CPU so, set in one Opteron280 in
socket0 update BIOS to v7.0 then put second CPU in)
Populate 4 memory DIMMs A1B1 A3B3
The RAID-0 should be set on NVIDIA RAID (FD is required)
With memory recommended above the simple over-clocking below does not
require any special voltage/timing tuning:
- The memory latency can be set to CAS 2.5 (2.5-3-3-8-1) (BIOS
settings)
- The CPU speed can be set to 215 (provides free upgrade to Opteron
285) (BIOS settings)
- Disable all spread spectrum options (BIOS settings)
- Set only basic ECC options (for all banks) (BIOS settings)
To speed up booting:
- Switch off all unused IDE
- Switch off Silicon RAID controller (jumper on MB)
The ASUS web does not have the latest drivers for NVIDIA chipset
I would recommend take the latest from TYAN website
http://www.tyan.com/support/html/drivers_support.html
* nVidia Chipset
* SATA RAID for nVidia nForce chipsets
The SATA RAID-0 has to be saved on FD in order to install Windows on
RAID ("press F6" procedure)
Drivers can be taken directly from NVIDIA website; however there is
some confusion what chipset package has to be used for k8n-dl.

Thanks, Stefan. Can you provide any temperature data?
Regards
Room ~20C
Under heavy load (16 computationally intensive threads) CPU temp ==
42-45C
Room ~25C
Under heavy load (16 computationally intensive threads) CPU temp ==
45-48C
The noise level of system is below 30db (~1m); close to what you may
expect from
6 X 80mm fan at 2500rpm.

If you have the caculations done, could you show the highest ranking
setup in some set of pricing categories; e.g. best for under $500, best
for under $750, best under $1000, etc.
$2500 is more than I can fund, but I need to run MATLAB pretty much all
the time, and I'm doing my best to try and find the best setup
available for that.
Thanks!
