GUI is rendered at 900p, fanartres and imageres are at their defaults. And I have no idea what gpu_mem, gpu_mem_256 and gpu_mem_512 should be.
Problem is, because sometimes when I am streaming online videos (youtube), xbmc (or just online stream) crashes, and I would say, that is because RAM, cache, or some other memory related setting.
If online streaming is crashing, it is too high a cachemembuffersize (see http://wiki.xbmc.org/?title=Advancedsettings.xml).
I'd suggest setting it to 0 so the sdcard caches the stream which will reduce memory usage. Otherwise set it to about 2M.
gpu_mem_512 is only used by a 512M board, so ignore that.
Set gpu_mem_256=128 would be my suggestion on Gotham. You can set it lower, but may have issues with some library views, or when playing 1080p video.
