I currently have DELL E5150 and a Intel 650 3.4 ghz processor and my mobo is a i945G/GZ Chipset, i did some research and it is possible to upgrade my processor to a Pentium D, Pentium EE, and even Core Duo.... but the Core Duo part sounded kinda fishy... so my questions is what is the best processor i can get that my motherboard supports?
