I have been holding off investing in some Quad core CPU's for quite sometime now as I knew they were going to be cut in price and I need a few for rendering.

Well, I'm happy to say they have finally been slashed in price and it's the biggest bargain I have EVER seen in computing. Seriously.
Potentially 11 GHz for under £170.00 quid. It's really insane.

The model I am referring to is of course Intel Core 2 Quad Pro Q6600 "LGA775 Kentsfield" 2.40GHz (1066FSB)

These chips can be easily overclocked on air cooling to gain even better performace and unlike AMD you don't need expensive, low latency ram to do it.

The cheapest I have seen them in the UK so far is www.scan.co.uk
