I have a AMD Athlon XP3000+ ,2.17GHZ processor in my old Studio PC. I would like to upgrade it. What processor/s are suitable? According to the SiSoftware SANDRA it is upgradable- Socket slot A, Upgrade inerface socket 462, supported speed 3GHZ. Can I use a dual core Athlon? If so which? The PC is a dedicated recording studio computer running cubase SX3 and many VSTs and Midi with no internet connection. Please help/advise. Thanks in advance.
