Hello, A dual processor G4 should run faster on most functions than a single processor G4. It anecdotally seems that my dual 1.25GHz MDD launches browsers and boots up faster than the dual 867 MHz MDDs at my workplace. Does a dual 1.25 Ghz MDD with 1.25 GB of RAM run faster than a single 1.25 Ghz MDD with 2GB of RAM? That is difficult to answer without knowing all the variables. If you were getting out of memory messages with a single processor MDD with 1.25 GB of RAM, then a dual processor MDD with the same amount of memory will still give you the same out of memory message. The dual 1.25 Ghz MDD's have a 167 Mhz speed bus. In a single 1.25 Ghz MDD, I think the bus speed is 100 Mhz, but I could be wrong about that. Taking a look at the performance monitor displays on both MDD's will probably give you a better answer.
