To me, that seems like an absolutely amazing resolution for many games. Very rarely do you need more pixels in the vertical direction (most games will just end up rendering sky or ground) when left to right are all you really need. That resolution is still fewer pixels than a simple 4k display, which modern games seem to drive at 60fps quite regularly if you buy beefy hardware. A graphical gore fest like Doom runs at over 100fps on 4k on the card the author has, so a mostly static city builder should also operate fine at a resolution like that.
