I just got a HP laptop from Comet for £350 should of been £380 but as I worked there I got a discount, but it has a 15.4" screen with a Intel dual core cpu at 2.0ghz with 3gb of DDR3 ram @ 1066mhz but, it can be upgraded to 8gb of ram for £100 which isn't bad for a laptop.
I use it for game admin software and web browsing etc, and it does it all fine and I even installed Call Of Duty 4 on it and it ran it at max detail at it's max resolution at 19fps minimum, not playable but not bad for a cheap laptop really.

You maybe able to find something cheaper than that, that will do what you want but that laptop is a little cracker really very happy with it myself.
In the description I think it says DDR2 or somewhere it says it but when I did the Crucial memory scan and also looked at the stick's themselves the scan, says DDR3 and the sticks say PC3 1066mhz so thats how I know its DDR3 which again is not a bad inclusion for a laptop of that price.
