I am deciding on which cpu, obviously. I will want to get a good cooling fan/ liquid cooler. For non-gaming use, 3d CAD, and multiprocessing, which gives more for a budget?

The i5-3570k has the highest overall performance. It is a fair bit more expensive than AMD's nearest equivalents but if you use your PC a lot, you may recover the difference on your power bills over the next 2-5 years. (Going with i5-3570k can save you as much as $50/year on power vs AMD if running close to full-load 24/7.)

A k chip is not really needed, you may save a few quid on a non k chip.

In the absence of any CAD based user experiences it is difficult to say which is better for you, a FX has relatively good productivity often in between the i5 and i7, so with that the logical and economical solutions will be between the i5 and FX chip, but maybe HTT is prevelent in CAD usage which may benefit you going with a i7. I will also say that Piledriver is out soon so maybe a Bulldozer is not the right AMD option to consider.

An AMD FX-8120 Zambezi with a FirePro V4900 would be dandy.

You could go in multiple directions with your motherboard and RAMs dependent upon your budget.

FX-8120 will be fine :) 

I'd pick 8120 over 8150 to save a few bucks.

I have been using an FX-6100 with no problems in games or other multi-media and productivity apps. Also, there were benchmarks that showed the FX cpu is just as fast as the intel k in the type of apps that you are planning to use.

Get the i5 2500k and overclock it.

Sorry, chum.

The FX-8120/50 is $145, and typically out-performs the 2500k in well-threaded applications such as CAD, 3D-modeling and video editing.

You might be right about that i was guessing on that part but i know for a fact i7-3930k >i7-3960x >i7 3770K>i7-2700k>i7-2600k all eat the FX-8120/50 for breakfast at a much higher cost of course :lol:

Heavy workload falls within the FX parts strength, loading up them cores makes it very happy.

Yeah.

It's one of the few things where the Bulldozers can be competitive. The OP should likely focus on a *pro graphics* card, anyway, being that the future is in GPU compute.

Workstation cards also have other app accelerators that make CAD work-flow much more enjoyable - from screen redraws and zoom functions to editing and rendering.
