im going to buy a pentium d 940 and there are options to either get it with 65nm or 90nm. my motherboard dont say either one of these for compatiblity, and i dont know which one i should get let alone what thiese numbers are for and what kind of impact they could have on me in the future. will somebody enlighten me thanks
 
The 65nm is the 940, and the 90nm is the 840.

The 65nm is the newest, it has more cache and they run cooler. I would go with the 940 (65nm).
 
Your going to have to match the socket type of your board to your CPU upgrade. Usually the smaller the die size the cooler and faster a CPU will run, I said usually but not always.

Note that if you want a more precise answer, then you're going to have to provide more information such as the make of your board.

my board that i will be pairing with this processor is a
ecs p4m800 pro-m via socket 775. i will have a ati all in wonder graphics card as well with 1x 120 sata and 1x 120 ide with dvd burner and 1 gig of pc 2700 ddr ram. i might upgrade to 1 gig of ddr2 533 ram...please give me as much feedback on all this thanks and is there a difference between lga775, and just 775 socket. can i use a lga775 in a 775 socket and should i still go for the pentium d 940 65nm?

You cant use DDR 2700 with a Pentium D, it requires DDR2 memory.

LGA775 is the real name for 775.

Personally i would go with the PentiumD 930, since its around $60 cheaper.

not necessarily, it requires a memory controller it can talk to. His board is a VIA based one that supports DDR and DDR2 as well as dual core.
