Laptop newb needs help.

Hey guys.
I have always brought components and built my own PC's but just recently I have a craving for a laptop.
I have never had one and am totally clueless about what im looking for.

Im looking to spend around £600 but would go a couple hundred over for a very good one.
Only £600? well yeah, I spent £800 a couple months ago upgrading a few bits for my PC so im not really looking to spend alot.

I spent a good 4-5 hours looking at laptops yesterday and at the end of it I thought my head was gonna asplode, I had no idea what was value for money or if it would be good enough for what I need :confused:

What I want it for is wow/other games/streaming vids/etc, would be very happy if it could run 1-5 copys of wow but that isn't a deal breaker tbh.

Any help would be very welcome and i'll love you forever :D

I shopped online for about a week and went to best buy and was looking around, this was also my first laptop, i didn't find anything i liked out on the show floor, the rep there pulled down a Gateway of all things and i checked the specs on it and it was a rockin laptop for gaming, it's the FX edition, has 2X 3.0 processors, 4 gigs ddr3, and a 9800 gtx with 1meg on video card ram, it's a nice laptop, just a gateway.
it was for around 1200.00
