I've got a HP DV6 series laptop and it has a Dual Core 2.6Ghz processor, 4Gb Ram, 512Mb dedicated graphics and a 320Gb hard drive. I know the hard drive isn't massive but you can get a bigger one and install it. I've got PSE9 and PS5 running on the laptop speedily enough and a nice bright 17" moniter on it too. There is a newer series out now, the DV7 which is even better by all accounts, but I'm happy with mine. It was about £450 when I bought it about a year ago and worth every penny.
