Hello everyone, I am new to these forums. I have read other topics on this same subject, I am still unsure if I can upgrade my CPU.

I have the big fat Optiplex 760, not quite sure what you guys call it. I currently have the Core 2 Duo E8500 and I would like to upgrade to a Core 2 Quad processor. Someone said this "The 0M858N motherboard should support Core 2 Quad CPU's" and I have the 0M858N motherboard in my 760. Should I pull the trigger on purchasing a CPU upgrade for this PC? It looks like I can pick up a decent used quad core for around ~$25 - $60 through eBay or Amazon and a few other sites that popped up in a google search.

Can I do it? Is a Q series CPU out of the question for me and my computer? Any help is appreciated. Thanks.
