Absolutly! More machines means quicker render times. There are a number of threads here about render farms and their effects on speeding up render times. (One includes a farm of multiple multi-threaded processors for something like 22 render nodes!) Do a search and see what you find. Personally I can't wait to get my new machine on line. Then I'll setup my farm with the old machine and a bunch of other new and old machines here at the office. (Just don't tell my co-workers... ok? ;) )
