...active PFC ...

had to google that - its 20yrs since I studied this stuff

Sorry, it was rude of me to use the acronym without explaining it.  I was taught better than that.

It seems as though the motherboard is a socket 478, while the CPU is socket 775.
Basically if you were to get the old CPU to work you would need a new motherboard.

your old CPU just will not fit into the old MB.  Didn't hurt to ask though.

Look at the bright side, 20 yrs ago you'd look up in the encyclopedia only to find out it was published 2 years before "PFC" was invented.

His CPU is more than likely a Northwood P4 HT CPU.    That is a 478 Socket CPU bro.

Ok one last question is the E8500 the best cpu I can get or is there a better one that will fit thanks guys!

He said if a E8400 would fit into a old dell...I thought the E8400 was a C2D 775?

Ok from what I can tell online I can use the Q9550 quad core cpu or the E8500 dual core cpu on my motherboard.  I really dont know what the differance is??  Would the Q9550 be worth the extra almost $100???

The dell is my kids computer mine is a velocity micro with 775 socket.  I was hoping when I upgraded the cpu on mine I could put it in my kids dell.  But I will have to get another motherboard for them.

You have to be careful.  Not all LGA-775 motherboards support all LGA-775 CPU's.  There have been three variations of the LGA-775 CPU's.  A BIOS update for the motherboard usually takes care of the differences.

Which is why I responded the way I did.   Skuzzy is correct, make sure your BIOS will support the CPU differentiations.
