About a year ago I counted myself lucky that I was able to order a heavy weight BTO laptop on company's account. 8GB Crucial RAM, 250GB Samsung EVO 850, i7 4612Q cpu, Full HD screen, NVidia GTX970, lighted keyboard and all that comes with such a high end laptop. 4 weeks later it was jacked from my car.... I still get angry thinking about it.
One of the reasons I left it in the car is that is weighs almost 3kg. Well I learned a few leasons at least.
Since then I build up a gaming rig which runs Windows 7 with a Steam client running. I can play any game supported in Steam while I connect with any system able to run a steam client. I even managed to play Minecraft while sitting behind a Atom powered netbook or a Raspberry Pi 2.
