Great to see so many people running SolidWorks on a Mac.  Have read many of your posts on here.  Thanks especially to Mark Biasotti's posts.

I'm planning to buy a used MacBook Pro, 2014 or 2015 model.

My only question: does anyone know which of the graphics card options would be best suited for SolidWorks?  I know none of them are ideal, but which would be best?

2014:  Intel Iris Pro 5200 + Geforce GT 750M

2015:  Intel Iris Pro 5200 + AMD Radeon R9 M370X

2015:  Intel Iris Pro only (no second GPU)

Thanks for any replies!
