Hmm. Well I would recommend trying it, I *think* HD4000 graphics should work, but you'll have to start up OBS to know whether or not it'll work. OBS requires that the graphics adapter supports directx 10, so if you get the "could not initialize directx 10 on [intel]" then you'll know that you probably need to get a better system. Your system probably isn't the most ideal otherwise but as long as it starts up you could probably still stream pretty decently, though perhaps not in HD.
