We could get new GPU servers (kipac's are old!) which are equivalent to bullet blads blades with ~5000 gpu-cores for ~10k each. So we could top off to 300k if we got 3 of these. We (PPA) do need to replace or existing GPU "system" that is hosted by kipac. A good case for adding some of these is presented here by Debbie Bard.
Pros and Cons of these options should be discussed.
