Is it possible to replace the lenovo Y50's GTX 960M to a GTX 980M?

What about if you already have some of those peripherals? For example, if I were going to build a new desktop gaming PC, I wouldn't need a monitor, keyboard, mouse, OS or SSD - I'd be using my old parts. Or, are you simply intending to compare all-in builds, that have everything included and is "ready to go out of the box" so to speak? Also note that I won't buy a wifi card for a desktop, I use Ethernet even with my laptops.

 

http://pcpartpicker.com/p/DtsDCJ - price is $2001.20

The 9870 from Sager with GTX 980, 16GB DDR4-2133, same SSD, Killer (I stuck with Killer since the motherboard comes with Killer LAN), 6700K, 1TB 7200RPM hard drive, IC Diamond, and the 1080p G-Sync screen comes out to $3354

The board I chose for the desktop even has X-Fi audio.

The 9870 - smaller screen, lower quality speakers, and the keyboards as we all know are garbage. I happen to own the keyboard and mouse combo I put in the desktop and I have zero issues with it. I don't even have it right next to the dongle. Its roughly 8 feet away. I also didn't go for the cheapest things I could get in the desktop either. The only thing missing is bluetooth and that's just because I'm too lazy to add a 10 dollar custom part for a bluetooth dongle.

There is no cost comparison when it comes to desktop vs laptop, the desktop almost ALWAYS is more bang for the buck.

EDIT: I actually changed the video card to a 980 Ti to make up for the 8G vs 4GB of VRAM. Price is $2195.19

 

Intending to compare all-in-all. Even if you don't want or need some of the items in a laptop, you still are paying for them, and it isn't fair to say you can get "the same or better" in a desktop for "Half or less" and re-use the same things you have from a previous system. No, that's not a full system. Bash what needs bashing but be fair about it, is all.

 

When I compared Paupsan his laptop I could build 2 equally powered desktops incl screen, keyboard and mouse for almost the same price but with a geforce 980TI instead of a desktop 980 in a laptop. THe only things that it lacked was multiple NVME SSD's. Chose Crucial SSD's isntead because they are more reliable.

 

That is totally subjective. To me a laptop will always be cheaper when you compare apples to apples. The reason is simple, because of all the R&D into making your desktop smaller you would essentially be creating your own desktop/laptop device anyway.

That means not only comparable CPU & GPU performance, but also they need to both be as portable as the other (a very important feature of “performance” for many of us). Both need to be able to run off battery for an hour or two (or more). Both be able to be used while waiting for a plane at the airport, carried to work with you, moved between living room and bedroom easily etc.

A while back I fired up my GT80 in my vehicle and made a copy of a borrowed movie, then returned the movie 30 mins later. All while on battery sitting on my front seat while I was driving. Try THAT with any desktop lol.

 

Ok, was just curious as to how you were comparing.

I know I could have built a way more powerful desktop for the $1100 my G751 cost, and even more so when I wouldn't have needed to spend $70 on a keyboard, $200 on a monitor, $90-100 on a good PSU or any money at all on an optical drive.
