Is there a way to have two i7-2600s in a computer. I have two i7-2600 desktops and was thinking i could combine the two for heaving rendering. Is this even possible?
Dual-socket motherboards are usually reserved for the top-end socket, 1366 currently and 2011 in the future. I doubt you will ever see dual 1155 motherboards, there aren't any dual 1156 motherboards as far as I know.
To put it simply, non-server CPU's do not have the functionality to communicate with each other. Opterons and Xeons designed for multi-CPU support have a specific feature which allows them to communicate with each other on a board, which is omitted in consumer CPU's and lower end server CPU's.
