So now that I can't use the borrowed 1050 I've been stuck with the igpu in my system. Which sucks, however I discovered you can get around 20 FPS on stuff like Jungle Island and other maps on low (not minimum) settings. So if you're saving up for a gpu and don't want to buy Beam until then go ahead!
I did play Beam quite a while with i3-6100 and iGPU before upgrading, playing 720p instead of 1080p is giving really big fps boost.
