Hi MrMotion,
Want to use it in a workstation, with CFD software that scales good over multiple cores. So want to put in the most cores I can, like 4X opteron 16-core chips.
GPGPU computing would have been better (faster) but the software (ANSYS CFD) doesnt support GPU computing yet. Quite a number of four cpu motherboards available already. Other option I have is to use Windows Server 2008, standard version does support 4 cpu's but is limited to 32GB RAM, Enterprise will do the job, but is very expensive. So well, I'm hoping windows 8 will support at least 4 physical processors. Windows 7 (64-bit) has a memory limit of 192GB RAM, which should be sufficient, but hopefully they increase that to at least 256GB aswell.
Having something like this in mind:
