[SOLVED] Is my Dell Latitude E7440 iGPU upgradable?

No, unless you want to buy multiple parts including gpu, psu , adapter. If you have used graphics cards and power supplies laying around go for it, then you only need the adapter like exp gdc : http://forum.notebookreview.com/threads/create-thread-e7440-geforce-gtx-750-ti-great-success.822497/

Is it worth it to buy them since i dont have any of those parts or should i just wait till this laptop dies and go for a new one?
i dont know much about PCs, sorry in advance.
 
You also would need to use it with external monitor plugged into the HDMI slot. If you get everything under 75$ might be worth it, might want to take a look into this adapter : https://egpu.io/forums/expresscard-mpcie-m-2-adapters/us7-50-generic-mpcie-egpu-adapter/ its around 5-10$ shipped (3-5$ for splitter), used dell da-2 25$ and you have about 40$ to use for used gpu.

https://egpu.io/ forums are better place to discuss egpu builds, just read about it first so you understand what your doing before going forward if at all.
