yes, it helps, but ...

Now the frontend "only" needs
  * support for the OpenMAX decoding acceleration
  * support for fallback to HLS when the MPEG-2 license is missing, the
    same goes for VC-1, WebM, basically anything that is not H.264 or
    MPEG-2
  * multiple rounds of making the OpenGL rendering more efficient
    (as has been done over at XBMC when they add support for other small
     devices, like the things that run iOS)
  * multiple rounds of making the frontend more efficient,
    e.g. theme/fanart caching etc. pp.

imho, it will depend on what you want to do with the GPU. Quoting from
our VDPAU wiki page:

   Many playback issues can be resolved by making sure enough memory has
   been allocated to the video card, 256MB is a bare minimum requirement
   and 512MB is strongly recommended. For on-board video this is usually
   configured via the "GPU Window" BIOS option.

With only 512MB memory for CPU and GPU it might get icky. Default
setting is 256 MB CPU + 256 MB GPU iirc.
Just run "top" on you box and look how much memory the frontend + OS
really take in your usage scenario (depend on theme, fanart, number of
recordings, etc. Now you know how much the frontend must be slimmed
down.
