Considering that MSI make some of best gaming laptops out there,the quality is fine and the laptop was around £800 for the model in the link to around £1000 for one with a better CPU.
On top of this spending £1500 on a gaming laptop is a waste of money considering the GPUs they have.
The fastest AMD card is the HD6990M which is an underclocked desktop HD6870 1GB graphics card which is more like the desktop HD6850 1GB in performance.
The fastest Nvidia card is the GTX580M which is an underclocked GTX560TI graphics card which is between a desktop GTX460 1GB and GTX560 1GB in performance.
Even with £1500 you can barely get a laptop with an HD6990M:
