Re: Pentium D or AMD 64
If it's a gaming rig... totally go for the amd. Single core is your best bet. Trust me... intel is starting to remake some new cpu's, and lemme tell you... the pent. D is not one of the remakes... just make sure it's socket 939 so you can upgrade to the dual cores for amd later on, like alvino said.
Macbook Pro and Logitech z5500s. All you really need.
