I am looking to get in to Pc gaming. I was think of getting a laptop as I would like to be able to game if I am away somewhere. But at the minute I am unsure of what graphics card I would need in my laptop. I plan on playing games such as titanfall, farcry, garys mod, Minecraft and hopefully gta 5 if it comes out on pc. My budget is about £1000 but I could stretch it if needed to about 1300. I was looking at a few laptops such as the msi gs70 with a gtx870 but would this be overkill. Please help me with what graphics card would be suitable for me and if you can recommend any laptops that would be good. Also is 17 inch or 15 better. I think I would prefer 17.
