I was looking to get the Msi gs70 gaming laptop. However there are a few different models with different graphics card. There is one with a gtx765m at 1050. One with a gtx860m at 1200 and there is one with a gtx870m at 1350. Is it really worth the extra 300 to get the gtx870m model or should I just get the gtx765m. Can someone explain what difference i would notice and if it is worth the extra money. I will play games like titanfall farcry Gary's mod and Minecraft if that is of any help. Also this would be my first gaming PC as I usually play consoles such as ps4.
