The main pc of my cluster is a dual Xeon X5680, 2 x six-core of 4.2 GHz (total 50.4 GHz), and Rémi's pc is 67.2 (12 x 2.8) GHz in total. Also the IPC (instructions per clock) of Gulftown Xeon could be slightly better than Istanbul Opteron. So, I believe the difference of the hardware is not so much.
