Anyway I am just curious, having beefed up my PC's memory and HD, everything seems processor bound now. I realise the mothorboard prohibits much scope to simply change processor without a new machine. But I cannot help thinking about what has been commonplace in commercial large scale computing for a while - the idea of having more than one processor. Does anyone here know if this is something that happens? It strikes me that the OS and Applications would need to be right, but with two (or more even) processors you could have a machine that really flew... Any thoughts?
