The graphics card, an Amd RX Vega 56, is nowadays one of the best there is. You can hit any game with everything activated in the graphics section as well as watch movies in the highest qualities or work in renders.
More exactly it is the 61 of more than 600 graphic cards.
Oh and be aware, if you're still using jack/mp3 connector, this model DOES NOT have it.
With that weight, more than portable, it is draggable. As long as your intention to move it does not pass from the desk to the sofa, it will do.
