I have a p37w v4 with a 970m and even the 970 is beastly. I'm sure you will love the 980m but I am curious to how well it will drive games at 4K so I do hope you update us on that! With that said, I did have one driver issue with mine out of the box. I had to install 4 or 5 different Bluetooth drivers to get it to work but all is well now. As far as heat goes, it certainly seems to get a lil bit hotter than my Asus g74 did but that is to be expected because the g74 had one hell of a cooling system and was much thicker. Important to remember these are low profile gaming laptops. Mine does not have heat issues. With BF4 and several other games I frequent maxed my temps hit mid to high 70's. The fans get loud as f*ck. I have never been one to get butthurt at the sound of fans but if that is something that bothers you prepare to wear headphones. So to sum it up, it gets pretty warm and I'm sure may even get "hot" as most gaming laptops do with a heavy load for long enough but I never have any overheating issues or anything like that. I ran benchmarks for hours when I first got it and although I don't remember the temps specifically, they were not to high to be of detriment to anything other than maybe a persons lap but I like to think folks understand this type of laptop is designed for a desk or table and not your lap. Let us know how it goes and enjoy that 4K!
