As you said, nothing new. I've been running multiple CPUs/cores for almost 10 years now. I have a friend who says, "I only use one program at a time. Why should I have more than one core?" Just looking at the process list shows that statement to be false, there are always multiple programs each asking for a little CPU time.
EAC wasn't even designed for multiple core support. It just happens because it launches the encoder as a separate process. Because one CPU is already in use, the next least loaded one gets the new process assigned to it. Simple, and automatic.
My current home computer has 8 cores (two Opteron Quads), but as soon as they become readily available I'm upgrading it to two Six Cores.
