Right, I haven't overclocked since my Duron 600 days !!! I picked up a Novatech base unit for £55 with the following; E3400 Celeron Dual Core 2gb DDR1333 80gb Sata Foxconn G41MXP (http://www.foxconnchannel.com/ProductDetail.aspx?T=motherboard&U=en-us0000485) Intel stock HS I have smashed the FSB up to 1066 from 800 with the RAM linked to SPD with no probs (3.45ghz from 2.6ghz) Stable as a bag full of stable stuff 2758 on CPU Mark from 1682 stock What is the best I could achieve with this chip? It's a 45nm chip, but is it a 1333 dropped to 800 by default? There is no voltage increments as far as I can see in the Bios Any HS to recommend (S775) for quietness? Intels drones on Would there be any real benefits buying a Q8xxx or a Q9xxx over the E3400? Thanks
