a 8600GT, 2.0 processor, 2gb ram and the 1440 screen can be had for under £650, not sure what the price is that comes up on dell site atm but i got mine quite a while ago for just over £600 with some haggling
I've just tried that config (currently with free upgrade to 3GB) and It comes in at £544 + vat and del. I think I might need two!!
If I opt for the 9 cell battery how badly does it stick out from the machine? and I can't find an option to buy an extra battery, is this not possible? as I read somewhere there is an option to remove the dvd drive and replace it with an extra battery.
