Just scanning through the Dell site and noticed this fantastic deal for a very high end laptop.
Click the above link and select "personalise" on the system on the far right stated at £599. Select it with the 1 year warrenty and proceed to the upgrades page. Skip the colour upgrade and go to processor, now I believe this may be a pricing error but the upgrade to the I7-720QM is only £89.99 (even though the dual core i7-620 is £210.00)
As title says this is a machine with 4GB of very fast DDR3 Ram, 1GB Graphics card a 500GB Hard drive and running windows 7. I am really finding it difficult to resist!!!! Snap it up before dell realises what must be a mistake!
