Lots of steam users are gaming on their laptop. And if you are a casual gamer gtx 1070 might be overkill, but extra performance -> longevity.
1070 150W TDP card will be the flagship mobile dGPU going into $2500 laptops. If you look at these so called "laptops" with a 980 card, they are basically 40 min battery life briefcases. These are not laptops - it's basically a $2500+ small form factor briefcase with a screen attached. It's cheaper to build a Raven RVZ02 i7 6700K and a GTX1080 and buy a separate 4K / 1440p 165Hz G-Sync monitor to take with you on flights for work .
On a more serious note, laptop gaming discussion has nothing to do with the desktop PC gaming space. But if you want to go that way, it's possible to build a GTX1070 desktop PC + monitor and get an good laptop with decent battery life for more or less the price of an overpriced gaming laptop that has an i7 6820 overclockable CPU + GTX1070 level card. OTOH, a desktop replacement laptop is garbage as a laptop (battery life is non-existent, screen is garbage compared to a dedicated desktop monitor, excessive weight makes it inconvenient for carrying around daily) and is slower than a dedicated i7 6700K OC + GTX1070 OC desktop. The main reason these gaming laptops exist is because parents of 18-year-old college students aren't willing to pay for 2 separate PCs....and many PC gamers have no clue how to build a PC with parts . Besides, the biggest laptop in the world is what 18.4"? That's honestly pathetic for immersion factor for spending $2500-3000 USD. Plus, if anything major breaks in the laptop, it's worthless junk or the costs to repair it are excessive.
Future games are going to leverage DX12 more. Why buy a new card that's not designed for the new API?
That's true but it's NV. If you buy an NV card, you know upfront it's for 2 years or less. DX12 games are still too far and few. We'll see what AMD has with Polaris 10. They still have a shot if they release Fury Air level of performance for $249 or Fury X level P10 for $299-329.
Even a gamer on a 1080P monitor stands to benefit from downsampling. Granted, the benefit is smaller than true higher resolutions, the quality improvements are far from negligible.
- Cannot magically reproduce extra immersion with 19-24" small monitors against 27-32" ones.
- Most PC gamers who are using 1080p 60Hz panels likely have TN junk with horrible whites, blacks and colours. You can render 1000 frames on that monitor, each of those frames looks terrible. Quality per pixel matters more than the number of pixels themselves --> Hence the entire reason OLED and HDR HDTVs blow away LED/LCD into the stratosphere
- Who in 2016 spends $400+ on a high-end GPU, has a $300+ i7 4770K/i7 4790K/i7 6700K but a welfare state
$90-$100 1080p 60Hz panel? Talk about not knowing how to build a well balanced PC. This is like buying a Porsche 911 GT3 RS and putting $100 used tires on it and going to race on the 'Ring.
Honestly, even 1440p 60Hz is becoming a bare minimum now for a high-end gaming PC in 2016. 4K IPS panels are dropping to
$400. The only reason 4K monitors aren't flying off the shelves is that even if one can buy them for $400, to get a great gaming experience would require at least 1070 SLI/980Ti SLI or greater which is $760+. Otherwise, 4K monitors are not far away from becoming very affordable. 1080p 60Hz is pure budget builds now and has been for a while. This is just a repeat of 2GB videocard owners defending those cards, dual core PC users defending those CPUs and of course 92% of PC gamers having budget monitors defending what they own. I had a 1600x1200 CRT in 1998, or
18 years ago.
