What would the 'best' CPU he could fit into that motherboard? I take it the Six core wouldn't work either then?
He plays Football Manager loads which uses loads of RAM and CPU but no graphics really, usual stuff though, internet, Office etc....
He's always got loads of things going on at the same time (encoding, Football Manager, office, internet, using his TV as a second monitor to watch stuff etc...) so just want to make things run as quick and smooth as possible.
