Simulation/Modeling/CAD Applications: i7-2600k or i5-3570k

says that the i7-2600k is not as good as the i5-3570k. Or maybe XEON E3-1220 , Xeon E3-1225 V2?

I am interested in benchmarks for

* ANSYS Fluent solver
* ANSYS Workbench
* MATLAB
* Autodesk Inventor
* Autodesk ALGOR
* COSMOS
* COMSOL Multiphysics
* CATIA/SolidWorks Simulation
* SolidWorks FlowSimulation
* Pro/E
* 3DSMax
* Adobe Photoshop

Also curious how the HD 7850 and GTX 660 Ti stack up against the Firepro V5900 and Quadro 2000. It seems they are better in single floating point but not double floating point precision.

Patiently waiting til October to see how Piledriver pans out though not keeping my hopes up.

I am not an Auto CAD expert but I do know for sure it's very CPU intensive and would make good use of hyper threading. The I5 has no hyperthreading and I would say the I7 would be better.

For CAD and mathematical modeling the i7 will perform better hands down, due to the hyper-threading as the above poster mentioned.

Again with the graphics, the professional series cards (firepro and quadro) are going to render and model much better due to better double floating point precision.

Gaming processors and graphics are great for gaming, but in a professional environment they start to stumble under the increased load.

The i7.
