I have tried some programming using benchmarks and have managed to exceed the theoretical GFLOPS - pretty good I'd say. What I am unable to do (with either my own code or other Benchmarks) is saturate my "GPU FB", I am yet to kick it past %40 ;( .

If I must wait that long I think I'll wait for the Netbook, can you imaging a "Netbook SuperComputer"!
