I have a sizable quantity of bare-bones HP 6570b ProBooks, and am looking at various CPU's to potentially install. The socket type is G2 and it has to be compatible with the Intel HM76 chip-set, but are there any other considerations I need to make?

You may be able to get a feel for the best speed tradeoff by getting the "Passmarks" for each CPU from http://www.cpubenchmark.net/, and then factoring in the cost of the CPU's.
