Best value laptop suitable for moderate gaming?

Basically I'm looking to buy a laptop as next year I'll be in my last year of college so will need to do work/ researching etc. So have found some pretty cheap basic laptops (I already use my iPad for work but it's not practical for coursework). However, I've also been quite a bit of a gamer, especially on the xbox, but I haven't been playing much recently, (and as I'm going to uni soon) I'd like to get a laptop which can handle games. I'd like to be able to play newish games such as ArmA and DayZ but understand that for a laptop it wouldn't be in the best quality, but that's fine.

After doing lots of research on the topic over the internet I'm now fully aware that it would be easier and cheaper to building my own gaming PC, however this is pretty much out of the picture due to needing to be able to move around for college and then uni and also my internet at home is not quick for downloading so I'd need to download games and software when at college.

So if you know of any good value laptops which can handle moderate gaming, and could help me to understand what to specifications to look out for I'd be very grateful. Again, I appreciate a PC would be best but it isn't a solution.
