Hello I am looking for a new 15 inch laptop to use for gaming. I would like it to have a gtx 980m. I would like a 1080 screen and I don't mind if there is a touchscreen or not. I would also like if the laptop gpu was upgradeable, although it wouldn't be a deal breaker. I'd like atleast 1tb of storage. Also I would like good battery life preferably more than 2 or 3 hours. I was looking at the sager np9752 for its upgradeability, but since it has a desktop cpu in it im doubting the battery life. I was also looking at the gigabyte p35x v3. I don't really mind if it is thick or thin but no thicker than 1.5 in. Also my budget is less than $2500. Thank you
