is it possible to join mother boards together to use both prossecors at the same time? And also i have apentium 2 mmx 233mhz prossecor it's won of the big black stand up ones and i was wondering if it would be possible to change it for a pentium 3 big black stand up prossecor or even a pentium4?

just get a dual-processor mobo what you're trying to do is have two computers (networked) together. You can't have more than one mobo in a case. Even then, you won't be able to have them divide up the work. you need a special mobo for that (and chip, but i'm not sure about that one) And you can't go to a p4...a p4 requires a different type of mobo. I don't know about p2 to p3 though and it's called a tower, not a stand up. There's the box that sits on your desk (desktop), and there's the tower that sits on the floor. There's also mini or slim towers, midtowers, and fulltowers.

I think He means a Slot A processor rather than a socket, u'll have 2 look at the motherboard manufacturers website 2 find out wot u can upgrade 2.

People with my problem! I have said slot A so many times when I meant to say slot 1. Slot A is AMD, Slot 1 is Intel. I have done this so many times before.
