Quite literally the same GPU I have plugged in...

02:00.0 VGA compatible controller [0300]: NVIDIA Corporation GK208B
[GeForce GT 730] [10de:1287] (rev a1)

Works great here! Only other thing I can think of is that I avoid
applications with the letters "G" and "K" in their names, and I'm
using xf86-video-nouveau ddx, whereas you might be using the "modeset"
ddx with glamor.

If all else fails, just remove nouveau_dri.so and/or boot with
nouveau.noaccel=1 -- should be perfect.

Cheers,
