Zip your just such a rude pr!ck to the noobs ...
If your not going to help them then I suggest you fcuk off smarta$$.
Its a simple enough mistake - most people would assume the socket fits and thats all they need to know.
Unfortunately in this case its a no go.
My suggestion Steve is to take BadTrip's advice and grab a cheap mobo that will support the E5200 which is a good overclocker.
Check you have DDR2 RAM in the old mobo first ... otherwise you will also need some RAM. Odds are you probably might have some DDR1 in it ... which you won't be able to use in a new mobo ... check that next and let us know.
