I would take a look at this; I am ordering this for myself in September. See what you think.

I will have more RAM, bigger SSD and no OS to come with it as a few changes.
Other changes too.
This is a huge laptop, very sturdy, metal body, 17.3" if you want a big screen. If you just wanted it to be portable in the sense that you would like to be able to pick it up and move it and have it in a backpack for wherever you move houses often or want to double it up as a machine you take out. I think it might be for you.
Of course if you're not going to buy it anytime soon, I can let you know first hand what I think of it come September; I've done a lot of research into it. (I'm also getting a ASUS x205ta for under 200 bucks as it has 14 hours of battery life, good for programming and word processing. Look into that and perhaps get a desktop instead of a gaming machine if you want it portable for work)
