Has anyone upgraded the processor in an EMachines T3508? If so, what processor did you use? Can a T3508 mobo handle a Pentium D or Pentium 4 processor? I've done all sorts of internet searches, and I haven't been able to find out anything about the mobo's Emachines uses in their computers, and I need to know for a friend who's wants to upgrade his processor. He's wanting to do some light gaming, and the Celeron D356 he currently has just isn't cutting it. Thanks for the help.
