Upgrading an Intel Processor From Celeron to Core 2 Duo

[SIZE=3][FONT=arial][LEFT]Hi there,[/LEFT][/FONT][/SIZE]

[SIZE=3][FONT=arial][LEFT]In my computer at the moment I have an Intel Celeron D 360(Single core) working at 3.46Ghz, but I’m looking to upgrade it for a bigger cache for better speed on my computer.[/LEFT][/FONT][/SIZE]

[SIZE=3][FONT=arial][LEFT]My computer is an EI System E206 (I know, incredibly old), also I have no idea what my motherboard number is as I’ve looked in vain for days trying to figure it out, so hopefully the information below is enough.[/LEFT][/FONT][/SIZE]

[SIZE=3][FONT=arial][LEFT]My info I have on my motherboard reads: UYJM71012761 PC P4M9007MB-8RS2H[/LEFT][/FONT][/SIZE]

[SIZE=3][FONT=arial][LEFT]My chipset according to CPU-Z is VIA.[/LEFT][/FONT][/SIZE]

[SIZE=3][FONT=arial][LEFT]I have three processors in mind, all Intel Core 2 Duos, but which one would be better for my computer to avoid overheating problems if any were to occur;[/LEFT][/FONT][/SIZE]
