When using CAD do u want more cores or clock speed?

[GoOakland]

Pretty simple question...its just I don't know the answer.

I have read that getting more cores is more beneficial for CAD here: http/discussion.autodesk.com/forums/message.jspa?messageID=6106765

But then I have also read that clock speed is more important: http/www.cadserver.co.uk/index.php?option=com_content&task=view&id=33&Itemid=34

Now the one about clock speed is back from '05 so I'm going to assume that its wrong now. But I don't know. If anyone could tell me some legit, current info about what to go for then I would appreciate it. If proof, like performance charts, is given then I would love to see it.

I can't show you numbers or charts, but I do know that the newer AutoCad 3d versions have their own rendering machines. I believe it is called Accurender and the newest one is Mental Ray, which I know Revit has.
If you are rendering in AutoCad, go for more cores (quad cores work best in my experience) but if you're only drafting, you won't benefit much from a quad core. A Core 2 Duo with 2.5 should be plenty powerful.

RAM seems to be the bigger issue with my machine.

Solidworks seem to say Quad core as a minimum and 2gig memory,but this is a parametric software so it might be different to other packages.
