Has anyone tried these processors:

Intel Xeon W-2125 (4Ghz, 4,5Ghz Turbo, 4core, 8,25Mb Cache,HT)

Intel Xeon W-2135 (3,7Ghz, 4,5Ghz Turbo, 6core, 8,25Mb Cache,HT)

Intel Xeon W-2145 (3,7Ghz, 4,5Ghz Turbo, 8core, 11Mb Cache,HT)

It looks like the 4Ghz processor has the lowest single thread performance.

Which one would you select, assuming you are using it for ?

no1. modeling in Solidworks, rendering and simulation.

no2. Only modeling in Solidworks

Are there others you would prefer and why ?

Thanks :-)
