I remember a friend who criticized me recently for buying a gaming laptop when he pointed out is expensive, poor battery performance and more. So i told him to meet me at a Starbucks 3 blocks from his apartment so we could play some games. Obviously he didn't show up and i was really disappointed not seeing him bring his desktop. That's the last time i heard him talk about my laptop. lol
Now that the laptops are out, it is entirely viable to buy a gaming laptop! (Woohoo!)
But it is still extremely expensive, and for college etc. for most people, it is still the best option to get something like a mini ITX desktop PC and a workstation laptop, as it is FAR better value.
Also @StoneColdSteve, how could you expect him to show up if he didn't have a laptop?
People own stuff for their own personal use, and if he's not on the move frequently, it seems obvious he wouldn't have a great gaming laptop.
Personally though, i'm not sure in what situation you could viably game on the go with a gaming laptop though.
I mean for a good experience you'd have to lug around a thick laptop with a mouse and mousemat, and additionally the battery doesn't last long, and the thermals are poor in most cases.
Only application I can see is frequent international travel.
I have an msi gt80 gaming laptop. it has dual 980 (m) cards running sli. I also have a rig with a 1080. Graphically in a benchmark comparison between the two on sli supported games my laptop annihilates my rig. If the game is poorly optimized or does not have sli support my desktop is better, but not nearly as much better. As far as pc gamers are concerned the idea of a gaming laptop is stupid. I disagree and have continued to put 90% of people's gaming pc's to shame with my laptop. Understand however, top of the line gaming laptops are between 3600 and 6000 dollars. 980ti desktop cards will continue to preform top class for several more years, and the only reason to jump ship to 1080s is for "future proofing". I assure you 980s including the mobile, and titans are plenty future proof.
