I am upgrading a server that mounts in a rack. Its going on the cheapest socket 775 CPU I can buy and in a 1u rack case. All its for is keeping some log files and doing some simple MYSQL/PHP database stuff. Not a work horse at all. Anyway, is it better to go 64bit or 32bit for the CentOS 5.x install? I do not see needing huge amounts of RAM or anything like that on this box. Would the 32bit version be more tried, proven and stable? Matt
