You will gain no advantage by putting a more powerful graphics card in your
mythbox that is acting as solely as a backend.  I suppose it is possible
that in the future, tasks such as commercial flagging and transcoding could
be offloaded to a powerful GPU, but that is not a feature now.  If that ever
happens, you could always upgrade then.

If you are setting up any frontends though, you should strongly consider
using a nvidia card capable of VDPAU, which will offload playback/decoding
for many CPU-intensive codecs and provides better deinterlacing than
otherwise available.
