Dell Optiplex 745 SFF upgrade

Trying to gather as much information as possible before investing in another processor that might even short out my system.
Reviewing my computer specs:

Processor, 80547, Celeron Prescott Desktop Socket T, 346 LGA, G1, Alternate. Socket 478
Intel® Celeron® D 533 MHz FSB Socket T with XD and EM64T (300 series)

im told to get only Socket 478 chips.
im told to get E6000 versions.
Socket 775, and even socket T,

The Manuf: suggested the intel Core 2 Duo, yet all i find is socket 775 no 478.
Intel® Core™ 2 Duo 1066MHz FSB Socket T with Dual Core technology XD, EM64T, 2MB and up to 4MB L2 cache, EIST and VT (E6000 series) (see the above line says socket T, and then E6000 series, what the heck is that translating to? Neither is 478 socket.

Or this one.
Dual channel shared DDR2 SDRAM system memory. Unbuffered, non-ECC DIMMs only
800MHz 4 GB (2GB per channel) 800MHz: 12.8 GB/s with dual channel
(800MHz not available in 2GB DIMM)

So whats the deal? Socket 478, E6000 series which house 775 i believe, or Socket 775. or socket T, who can be trusted?? Im assuming the 478 socket can house the 775 connection. but i really dont know.

please help.
