Hi. I don't see why it shouldn't although it may be overkill if you're using it strictly for CAD. I'd be more concerned over the OS, especially seeing how much a pig Vista is as well as the imminent release of 7, as I don't think the CAD functionality would make very good use of the multi-core architecture. Personally, if it were up to me I would rather invest in slightly more cost-effective CPU but bump up the graphics card, but, hey, that's just me.
