I may have to try this on my old T420 - will not be nearly as fast as your stuff but it does have 12GB of ram and a decent SSD. I have the dedicated Nvidia graphics card though which sounds like it may cause problems.....

I think that it would run fantastic, my Lenovo had dedicated Nvidia graphics and it worked like a charm. The AMD APU (Vega graphics) have been a horror show.
