You're all around it, BAP, and let me give you the good news. It's not 8900 that's key, it's the new Core_17 that uses the latest CUDA code that NVidia Kepler video cards use to full advantage that's key. And QRB in there to boot.
And you're thinking, that's just wonderful, ArVee, more mumbojumbo and btw where's the good news? 
The good news is that it's Core_17 that's doing the magic and Core_17 processes more than 8900, there are about 10 other projects that are released already, you just haven't seen any. So you're not going to run out, Core_17 is the future and the future is now. When 8900's run out, there will be lots of others. It's the stuff the rest of us are folding that will run out as the science progresses, they just won't run out for a few years and the points will be small compared to what you and Sun are doing.
So you guys are in good shape, it's the rest of us that should know this stuff for when we decide to upgrade.
