My computer is pre-built, so I'm going through CPU-Z for this. It says my motherboard make/model is a Dell 088DT1, and I would like to know if I can upgrade from a Core-i3 to an i5. I've seen other computers on Dell's website that are listed with the same motherboard and have i5s, but I'm just making certain. I know I'll likely need a new PSU, and that will be coming first anyway. If you need any more info, just say and I'll edit it in. Thanks in advance for any help.
