I chose the Asus PC brand, because I work a lot with software audio-visuals. so I needed a good memory RAM, a good graphics card and "a large screen. R751LN-TY143H Premium Asus Laptop 17" although pricey though, perfectly meets my expectations. For PC 17 ", weighs only slab, therefore easily transportable. It is worth its price. Only bémole condemned battery. So I can not take it off when I work on sector.
