Can i upgrade graphic card of envy 17?

[p_sahilnaughty]

I have HP ENVY 17t- j029nr running windows 8.1 with 4th gen i7-4900MQ processor and 16gb ram.

Currently I have nvidia GT 750M- 2gb graphic card but its still slow for few games, so I want to replace it with GTX 780m 4gb or upcoming GTX 780Ti 4gb . I dont know whether these graphic cards are compatible for my laptop. But I know that graphic card capacity of this laptop is up to 4GB. CONFIRMED. 

Can anyone please help me?

It will be highly appreciable and thanks in advance.

Wish we could help but there is just no upgrade path. The video is part of the motherboard so there is no video card to remove, upgrade and replace. All but a very few laptops are this way.

Thanks for replying but I have 2gb dedicated graphic card . Its not integrated with motherboard, that means it can be remove or replace. Even company HP says it has max swappable capacity upto 4gb.
Thats why I decided to change its graphic card.
I just want to know whether nvidia gtx 780 graphic card is compatible for my laptop or not.
I think it should be because the same graphic card and same 4th gen i7 processor is present in alienware M18x series.
As you are an expert Mr Huffer I still need your help in case of compatibility. Yes or No
Please help and once again thanks in advance

It is dedicated but still soldered to the board.

You are not getting my point. I know how to separate both of them. i have did it before in other high end laptops.

I want to know that will gtx 780 m card work with my laptop.

Well then you need to share that with the Forum. How do you separate the video cards? Where would you buy the upgrade card? I can show you the diagram of your motherboard if you give me the exact model number and there is no way in blue blazes you can remove and replace any part of the video system without replacing the entire motherboard. You may be able to in other very rare laptops, not this one.

I am pretty sure this is your Service Manual:

Service Manual

It shows the graphics system as part of the motherboard. There is no mxm video card part. See Page 23. The best graphics offered is the 750M.

HP ENVY 17t-j029nr quad core is my model.
I can buy graphic card from ebay or amazon.

If it cannot be replaced than what is the use of company providing upto 4 gig of capacity.

Have a look at this link and check 'video graphics' section.

This is my 1st laptop.
I have customised this laptop at its max level of what HP provided but as graphic memory is not upto the mark and it cannot be replace acc to you than what's the point of having this laptop. All my money is wasted and no proper satisfaction.
