Would that work for CAD rig?

he's using solidworks, which actually has CUDA support for rendering, I think. and I think we are talking about different work than revit does.

which xeons have HT?, im looking at the 1366 westmere chips which dont seem to show they use HT

EDIT: ignore me, was looking at the 80watt and not the 90WATT westmeres

solidworks is very close to inventer and if he is just using solidworks he wont need massive power. an i5 will be more than enough on the intel side

true, but he said he does rendering too, with photoshop and other stuff

also, red drives are fairly slow, 5400 rpm, blacks or RE drives are the best choice for this, short of a massive ssd

Thanks to everybody for the advice.

I was looking at the FX8350 again and it got me thinking, I guess it will come down to what I will be able to afford.

GPU wise I will have also another look into consumer cards vs workstation cards as I might got fixed on the "proffesional" cards too quickly.
