Atleast go with a pentium D there cheap and they run pretty good. I bought a processor and mobo from frys for like $85 bucks as a package. Ya the mobo sucks but still it will get you up and running then you can just upgrade little by little like i have been doing.
dont think i could of made it any clearer, i have everest program, tells me all about my cpu except what socket it is, i did ask "how do i find what socket my motherboard has".
