My use is currently mainly in photoediting and occasional streaming or videoblogging. I do light gaming with time constraints. After the cpu started overheating I haven't been able to play or stream.
I just checked it up, and it seems the Haswell is quickly coming to end of its limits compared to new processors. Well it was bound to happen. Maybe I'll upgrade one day. But for photo edits, it'll still do nicely for a few years.
Even my laptop, a Lenovo T500 from 2008 is still usable, while I guess it has similar kinds of problems with overheating, and the battery life is abysmal. Can't use it for photo edits no longer, but as a general purpose traveling office it has served me well.
