You can wait for ivy bridge, then stick some Kepler GPUs (nvidia gtx 680) in it. That should max the performance. asm is pretty much stagnant for general purpose procs since core2 came out.
Is this true? To my knowledge, the Fermi GPU (GF-110, eg. GTX-580) is a 16 processor (streaming multiprocessor, SM) system, each processor having 32 cores running at 1.5 GHz, and the Kepler-1 (GK-104, eg. GTX-680) an 8 processor system with 192 cores per processor at 1GHz. Because on the Fermi each SM has more L1 cache than each SM on the Kepler-1 and because it might be harder to saturate 192 cores in a compute-scenario, I'd expect the 580 (GF-110) to be significant(?) faster in the next Gromacs (4.6). Maybe somebody tested this already. (Here in Germany, I can by GTX-580/3GB for ~325€ + Tax.)
