If I remember correctly (and I often don't), there might have been an Intel hardware patent gumming up the works. If you want to have multiprocessor support, you will also need to get a different (read: more expensive) motherboard. I'm pretty sure only the HX chipset supports this but not all HX boards have two sockets. Bottom line: unless you are planning for multiprocessor support I would not worry about it. If you do plan to use multiple processors then you will need a different motherboard and CPU. While we are on the subject, which multiple processor board is recommended these days? I personally do not need EISA support and would prefer not to pay for it. Does Asus have a multiprocessor without the EISA? ====================================== When philosophy conflicts with reality, choose fantasy.
