Update on new GPU core

Several people have been curious about any news regarding a new GPU client/core.  We hit a few snags and then hit the holiday break, but the team is back
now.  We have the new client running in our lab
and we’re doing some final Q&A on it. The new code is running on the latest ATI cards (2xxx and 3xxx) and getting pretty good performance so far. The performance is pretty
good now (after some optimizations from Mark and Mike H.), so I’m
optimistic. This does not look like a 6-month delay, more like a few
week delay, but it’s hard to tell — you can’t predict the
unpredictable things which can come up.
