The guy with the MSI laptop seemed to fishy.
Went with the Asus Zenbook pro, got him down 75$ which i'm going to use on additional 8GB RAM.
Found it it had 8GB soldered onto the motherboard itself and one open slot DIMM slot. So it is actually dual channel

I'm sooo pleased with it, first of all the simple and clean design. But overall great display, keyboard, trackpad and amazing performance.
