workstation motherboard help!

hey guys, this might be a newbie question. But i am trying to get a workstation type computer for 3d rendering and graphics applications. But at the same time I would like to be able to do some gaming on it. Does anyone know of a motherboard that can support 2 cpus and also have sli or crossfire capabilities? Thanks alot in advance!

What program(s)? I advise double checking what the CPU support limit is, as for some rendering programs you are capped at 4 cores.

Also what resolution do you run your monitor at? SLI or Crossfire may be overblown.

I would doublecheck with a reseller (or autodesk, but I find the VAR"s are far more helpful), I know of a few Autodesk applications that are capped at 4 cores. Unfortuantely the products I am more familair with are on the Civil engineering side (i.e. Revit, Civil3D, etc), but I'm pretty sure 3DS will sue more than 4.

Looks liek Adobe Premier will use 8:

For what (it sounds like) you are looking at I would make sure to get a 64 bit OS with tons of RAM (8GB maybe, I'm assuming your projects are complex).
