First Multi-cpu rig build, need final advice ( 2 Views )

1. Hi! I am starting to build more and more computers everymonths for friends/clients and today i have a nice request from a guy who works in the CG industry who wants to do occasional gaming and basic 3d rendering/photoshoping. He wants a dual cpu rig, less then 1000$CND.
   
   It would be my first dual cpu so thats why im posting it in case i misunderstood something.

   Questions:
   
   Would it be better to have 2x512DDR ECC instead of 1x1024 ? Is s940 fully support dual channel ?
   
   This powersupply says it supports EPS12V, is that the name of the 8pin connector needed?
   
   any toughts?
   
   I am happy to build my first dual-cpu rig because i am planning to build my own in the following year for dual opteron dual core, i will take that as a learning exercice.

2. Not sure about the questions you asked. The opterons do support dual channel memory, but the impact of having it can vary a lot, though there's no reason you shouldn't make use of it.
   
   For a dual processors, you will need 2xx opterons. The first number indicates the number of processors that can be used together. 1xx opterons are for single processor systems, 2xx for up to dual processors, and 8xx for up to 8 processor systems.

4. Hey, just out of politeness you shouldn't post the same topic in two forums. http://hardforum.com/showthread.php?t=1030490 should have been more than enough.
