Yes this is suitable,
I have a ThinkPad X201 tablet as a secondary laptop,
i5 520um 3M cache 1.07 GHz max 1.87GHz
Windows 7 32 bit
Intel HD graphics 166mhz 1273mb memory (yours would be better)
I have solidworks 2013 on this computer since 2015 doesnt have 32 bit version, but im gonna expand to 8gb ram and clean install 7 64bit then ill put 2015 on here.
I have been able to model on here fine and even do somewhat intensive simulations.
Even with only 3gb ram the resource monitor stays green.
The only problem i have had is the dynamic highlight, which can be disabled in graphic view but it insists on doing it when selecting things
for a feature, it will trace the edge of the selection and highlight it, and if its complex it will take a few painstaking seconds to finish tracing it,
but that probably wont be a problem for you since your intel graphics will be newer
When using an non-certified graphics card, results can be widely varied. While Ryan hasn't experienced any issues, you may find the opposite to be true. You might want to look at the Dell factory outlet site for good deals on mobile workstations: Dell Factory Outlet
just remember though, Lenovo is lyfe
My personal experience is Ive used solidworks with 4 different "non-certified" GPU's with consistant experience that reflects the specs of the GPU.
never use an Intel graphics
On my laptop I have two, an Intel Grapics and NVidia Quadro with 4 GB memory.
Invest in a good graphics board like NVidia Quadro or Ati Fire Pro/GL and no other shit
