Valley benchmark https://imgur.com/a/bdnIPnM
Tried with Destiny 2 and Battlefield 3 both on max settings in FullHD resolution (1920x1080) on the notebook's internal display, getting 35-50 fps in Destiny 2 and around 40-50 fps in Battlefield 3.
Both very nice and playable so far.
Will be more than glad to get comments, especially how to improve performance of this build if possible.
Strange thing: fps is almost always around 50, goes up to around 80 only if I lower the game resolution - this is valid for the internal display.
I think the limiting factor must be the bandwidth of the expresscard interface.
I found out later on that the internal display is really limiting the performance (see Valley benchmarks above, internal vs external display -- scores 1500 vs 2000 points)
