I will be getting a laptop this week from PC World/Currys. Can anyone recommend a decent one that will run Football Manager 2012 well and in particular the 3D Match option?


Any help is much appreciated


Edit - Have set budget between £300-£400
 
I hear it's inadvisable to keep your laptop plugged in (on charge) all the time? How true is that?
