What's your budget, Shiny? Do you want to get a very good desktop pc coupled with a cheap laptop for mobility, or would you rather put all that money into a single higher-end laptop? Keep in mind of course that gaming laptops are usually very clunky and often unattractive to use on the go. They have less battery life, make more noise, and are probably gonna be uncomfortable to use on your lap.

Personally, I like really small laptops with good battery life and very limited gaming performance, coupled with a good desktop.

Spuuky's site is pretty good. I'd say the superb/excellent range is probably what gets you the most bang for the buck. Going for something that costs twice of that will probably not give you twice the perceived performance/quality. At the same time, halving the cost from that price range is probably going to reduce your performance by more than half.
