I am getting very alarmed by this discussion as we just took delivery of ten 2x quad core systems to be deployes as heavy webservers in order to replace the dual core ones. probably under 7.0 as 6.3 wont boot PAE and they have 16 gigs of memory. > Anyway I'm happy that I'm not alone with this problem.
