All the advice has been great guys, I have some more questions if that's alright.
I have a budget of about £2000. I could go over but I would rather not.
A real issue I have had is overheating. My Laptop crashes at the first sign of stress which makes video rendering a real pain, so laptop with good cooling a must.
Secondly I see a lot of the suggestions have been the MSI GS60,70 or GST70, is there a reason that you guys suggest these over alienware?
I've been looking at Overclockers Notebook section. There are two MSI Dominator's to buy, but I cannot see the difference between them. Anyone noticed them?
Finally, in the Desktop Gaming area there is generally a fall off point, where it is simply not worth the extra thousand, because the performance is just not going to be improved much further. Is there a cut off point like this for laptops? I notice that no one seems to be buying the Overclockers "OcUK Express Ultimate P570WM3 17.3" LED 3D 120Hz Full HD Intel i7-3930K, 32GB 1600MHz DDR3, 1x 256GB SSD, 750GB HDD, NVIDIA GTX 680M SLi 8GB GDDR5 Graphics Card - Windows 8 Pro Hardcore Gaming Laptop" I know it's a good rig, but is it worth that amount and will the performance really be noticeably higher than the £2000 MSI's?
Also has anyone tried to build their own laptop?
