I played simcity since late 2013 until a few months ago, but, since no matter what i did, the city became unsustainable because of incredibly heavy traffic at about 220k - 300k pop. I always had a blast when beginning to build my city, but it just became more work and less fun later on. Then i just decided i'd rather get skylines instead.
I'm also not aware of any maxwell issue with this game. I have a gtx 970 and have had no problems with graphical glitches.
