One would expect a 64bit processors to be used only for server side work mostly. Windows2000 Adv. is currently the server standard from MS. Mckinley was being sold with win2k pre-installed. I dont know if win2k supports 8processor system (why shouldnt it?), but than again, we dont have that type of system existing currently to support. So we dont even have a 8-processor system yet for Chessbase to use :) cheers, pavs
