Hey. My friend who lives in UK wants to buy a laptop.

Question1: Where should I look for these laptops aprart from ebay and amazon? What good internet stores with nice product range would you recommend?

Question2: What brand, what to avoid? MSI, Lenovo, Asus are good? Acer to avoid?

For: Bit of gaming, photoshop, movies etc.
Budget: 700-800£
Preferably: I7, 8-16GB Ram, 15.6 - 17 inch, good GFX (Which? Have no ideas about laptops GFX) + SSD hard drive if its possible, but there are so little laptops in this price with these.

Please halp :)

Links would be nice.

Thanks
