G900 I'd say  
 
The QCK(+) is probably the most tried and used mouse pad available so ya know, there's probably a reason why so many people like it...

So...what games do you play?
Need macros?
RGB?
Hand size?
Preferred grip?
 
 
Anyways, go to a store and try out different mice.  A G900 might be great for you or it might be horrible.  Popular mice : Zowie FK or EC series, Razer Deathadder, Logitech G303, G403, G502, G Pro, Steel Series Rival 300, Nixeus Revel, amd ,amy more.
Mouse pads are a matter of preference.  I have used the Steel Series QCK Heavy for several months and I love it.  Some prefer a faster mouse pad, some like them with dogs on them, etc...

That is up to you

Still a few things that need changing.
Get the GSkill 2x16gb 3200mhz. 
Do you really need the 512 HID approved drive?
Get the new huge power adapter 780w one instead.
Get rid of the EVOC logo. 

turning SLI on and off doesn't impact battery life that I have ever found. The GPUs still are powered on. Just keeping em at idle is best, and less hassle.
What is "load"?
1.5-2 hours, maybe 2.5 hours if you're lucky and set the machine well. For some odd reason my 7700K won't downclock at all, so I can't properly test that for you even if i wanted to.
Having a HDD installed and active will hurt battery life a bit more than a full SSD system.
 
You say price is not a factor? Then I'll fix your config:
 
960 Pro for OS drive over 960 EVO (MLC is best). Manually take the 850 EVO drive for your 1TB (unless you can afford the 960 EVO). Don't use the HID approved. The 3D V-NAND is worth it, I can't guarantee you'll get 3D V-NAND from their approved drives.  Why are you getting a second NVMe drive? Especially one that isn't known? 2TB 5400 RPM drives are very slow, they're only for storing large amounts of static files (like movies or pictures or videos). Do not use for games. They also will hurt your battery life. Message them and ask for G.Skill 3000MHz instead of 2800MHz. It'll cost a little more. Get a 3 year international warranty if not in the US. If in the US, get a normal 3 year warranty. You want it. Get the 8265ac wifi card instead of the killer. Also ask if they can install the bare drivers via device manager instead of the Pro/Set Wireless combination. Get the 780W PSU from them. It's worth it. You want it. I'm guaranteeing you that you want it. Forget the cooling pad, buy and modify a Notepal U3 if you want one Forget the backpack, buy (or select if they offer) an Everki Titan if you need one. Tell them, specifically, to only install Clevo Control Center *WITHOUT* XTU. You and your fans will thank me later. And that is that!
 

Yes. And for reference, please use the Clevo tags, P870KM1 and P870DM3. It's just alot easier when discussing Clevo laptops because Sager brands them differently, origin brands them differently, myth brands them as the phobos, and basically there's too many names.
 
And never buy from Origin LOL. Not laptops anyway. There is literally 0 reason to get it from them. 0. I literally challenge someone to find a reason. It's overpriced to hell, doesn't have the proper bios, you can get cheaper, better parts, better support elsewhere.

^ this is actually the laptop so look here.

Alright this is the closest comparison to your laptop http://www.anandtech.com/show/10795/the-clevo-p870dm2-mythlogic-phobos-8716-laptop-review-dtr-with-gtx-1080/6

0_0.......with dual 1080s and the fact its custom its hard to say

You can get CPU's with more cores + quad channel memory and usually more RAM slots.

Yeah, but if he is just going to be gaming, the 7700K is the best option, if he is is doing video editing, 3D work etc. X99 will be a better choice. 

I'd go X99 with that kind of lay out:

Don't get an external drive if you plan of using it a lot. Just get another internal drive and keep what you need to carry with out on a flash drive. You also might want to wait for ryzen if you can.

Can you not get a 4x8GB set of G skills ? 
But anyway a that pretty similar to my build except I use a H80i V2
 
terms of custom thermal paste, the H100i has a pre applied layer of Corsair's custom thermal paste 
 
case selection, with what you've got, any standard sized mid tower +  will work, so it's up to you to pick one you like,
 
cooling, well depending on how many preinstalled fans, you wouldn't be needing much, just enough to comfortable pull air in and. Push it out 
 
build should last you many Years going forwards 

don't buy from Amazon india ....... their price is stupidly high.
where you live in india? ..... if you live in metro cities you can find stores which sell pc parts, there u can find some good deals, for ex. if you live in delhi go to nehru place and if you live in mumbai go to lamington road.
 
if you can't buy offline then buy from ....
 
primeabgb.com
mdcomputers.in
itdepot.com
golchhait.com
itwares.com
 
newegg would also be not a good idea as u have to pay a lot of shipping charges 
 
also i would suggest you to go to r/IndianGaming if you are on Reddit as i have seen many people post their builds there, like yours, so they will surely help you where to find good deals.
 
2300$ is a lot for 1400$ build.

it is bad but not that bad ??.

yes ik but things in asia can cost way more than that.

That would be an awesome build and a beautiful one at that, around $1600, making it last easily for at least 3 years.

my bad.
Case- Phanteks Enthoo Pro M 
AIO cpu cooler- Corsair h100i v2
You don't need to apply thermal paste on anything, it comes pre-applied aio cooler & this build is definitely future proof but if you want the latest then you have to wait for a couple of months for the kaby lake architecture (i7 7700k). But the performance difference won't be huge.
