I had to move abroad for half a year as part of my university degree and had to buy a laptop for gaming, making music etc.
Went for the MSi Ge70. Cost over Â£1000 but I'm planning on selling it when I get back.
The specs are:
CPU: Intel Core i7-3610QM
VGA: Nvidia GTX 660M / 2GB GDDR5
1920x1080 17" Screen
Ram: DDRIII 8GB
Works like a charm with pretty much all games. Running battlefield 3 on low at 1920x1080 and getting around 60fps. Runs all other games I play fine to such as Natural Selection 2, Dead Space 3, Age of Chivalry, CS GO. In terms of visuals it's pretty nice, haven't really had any trouble except with Crysis 3 which didn't run properly at all and look ugly..
Also works well with Source Filmmaker. FL Studio works fine too.
Only thing is, you could probably get one that suits your need for a cheaper price. I bought this very last minute as couldn't take PC.
