My newest laptop also sports an integrated Intel HD 4400 chipset for video. Runs fine on some games (mainly on ones that aren't graphics intensive) while those are extremely graphics intensive (which are becoming common again) will have problems.
Even though, I primarily use my desktop, I have definitely found great use for Steam's In-Home Streaming in the event I am not on my Desktop, but elsewhere in the house with my laptop. Most games work great on it (with a few exceptions such as Watch Dogs, which is notorious for having low framerates). It only hits around 30fps on relatively high settings @ 1080p and it should've run fine on the nVidia Geforce GTX 760 considering there was a promotion getting a free copy (I got my copy that way).
Off-Topic: Do not even bother going 4K through Watch Dogs on High settings on an nVidia Geforce GTX 760. It will become extremely slow to the point you could barely navigate at all. This is for those who enjoy playing around with DSR (Dynamic Super Resolution) or have working 4K monitors.
Back On-Topic: Yeah, I have found great uses for laptops for home use outside your desktop area. Heck, I have gotten a very old laptop from 2008 to run well through Steam's In-Home Streaming (though may have a bit more trouble with some games due to being an older laptop in general). I do, however, still run games on my laptop without streaming.
