I would like if I could get your opinions on the following desktop and laptop configurations I'm considering for our department. I'm told the price isn't a concern (within reason I'd imagine i.e., no 14 core processor) and we have to stick with the Dell brand. Our current configuration is a T3600, Xeon E5-1620 @ 3.60GHz, 16GB RAM, 256GB SSD and Quadro K2000. Based on the options available on Dell's website, here are the configurations I'm considering for our next upgrade.
T1700, i7-4790 Quad Core @ 3.60GHz, 32GB Non-ECC RAM, 512 SSD and Quadro K4200
T5810, Xeon E5-1630 Quad Core @ 3.70GHz, 32GB RAM, 512 SSD and Quadro K4200
M6800, i7-4940 Quad Core 3.10GHz/4.0 Turbo, 32GB RAM, 512 SSD and Quadro K4100
I'm not up to speed on all the deep technical aspects of the components but much of the research I've done seems to lean towards the fastest i7 processor. With that said, I am somewhat confused because Dell recommends the T5810 with the Xeon processor over the T1700 i7 for SolidWorks. Any suggestions or recommendations from the SW user community is very much appreciated.
Some details about our environment - We create some pretty complex designs and large assemblies with SolidWorks. We also use some Pro/Engineer and AutoCAD, and most if not all users will also be running some form of Office, SAP, Enovia and internet applications at the same time. All users have a Dell U3011 monitor with one or two smaller monitors. They will also be given the option to chose a laptop/docking station over a desktop when upgraded.
