I need some recommendations for a P4 setup for a guy who wants me to build him a new machine. I switched to AMD long ago so I'm out of the loop on which chipsets are considered the best. He wont be using WinXP so Hyperthreading could be taken or leaven. The thing that is the most important is stability & reliability, it'll be a business machine and won't be used for gaming nor overclocked. Also, how are the stock Intel heatsinks with the retail procs nowadays?
