My Bro has a laptop that doesn't work, due to the fact the pin in the power socket has came out. It's been left alone for ages and I've just had an idea. I'm not that good at electronics but I think i might just have an idea here.

I find your choice of components very good and I would therefore say you'd be able to do about 3.5ghz+, unless of course you don't have a very good e6600.
