But I have one, important question, what about processor i7 5500U? I know, that its only dual-core processor, but when I want quad-core processor and I dont want to go into desktop I need about 1k Euro+ pay for notebook and its so much for me . So my question is: Have anybody experiences with this type of processor in the meaning of working with CAD systems on this type of processor? And its worth it to pay about 300 Euros only for quad-core processor?
