Yes! It will work! PCB of gtx765 and gtx860 are the same size and fittings so it should be bolt on. IMO Gtx 770 is better than 860 also it has more vram and cost the same.
Similar question, here. I have the 770m right now but in a year or so I want to upgrade to the 880 or 980. Will they fit?
Guys, while all this talk of upgrading a G750 to a newer / larger GPU is interesting and exciting, noone has every done it successfully, ever.
So I would get the idea out of your heads and back into the reality of getting the most out of the laptop you have, and take good care of it for eventual resale or passing on to a friend or relative that can appreciate it.
Hacking it up to try to make work a GPU upgrade isn't the best way to treat your laptop or spend $$$.
Save up for a new G751, or what comes after it, and pass on your current G750 to a friend or relative that will appreciate it.
The G750 was built with replaceable parts for easy build and service, not for upgrading.
I put a g750jx board in my g750jh the story was like this:
code9523, you are talking about the other end of the horse 🙂
You replaced a motherboard, now think that all the motherboards are interchangeable, but they aren't the same, the are different according to the parts built into/onto the motherboard. The BIOS will load, and not find some things, but find others, and appear to work - it may be enough - it may not be enough.
Just because the basic blank board is the same doesn't mean it is built out the same for every model.
The other end of the horse is of a completely different color.
Replacing the motherboard with a lessor model isn't the same as swapping in a larger hotter more power hungry GPU into an inadequate host system, that has less support for high power and higher temperature components.
Just because all the laptops use the same battery, motherboard blank, other parts, doesn't indicate you can put them together as a whole by doing a Frankenstein build and it will look like Marilyn Monroe when you are done. 🙂
And, the reason I am following up on this is because there are lots of less experienced people out there that will take the bait, and try to do it for themselves - because they want so bad to install a 980m/880/780m in their laptop - but it won't work.
They will have a basket of parts, receipts for things they can't return, and can't sell. And at the end of the operation, the patient will be a fugley'stein and not work.
Please don't encourage them. 🙂
