HP Elitebook 8570W - is it still good ? Hardware modifications

[GuitarG]

Little upgrade, after dissasembly of panel I put some thermal pad for big IC of DC board - I cut out plastic foil between lid and IC. Now panels seems to be cold, previously it was very hot to touch (especially on lower bezel). Will test more with higher brightness, but seems to help somewhat - I though previously that RGB backlight of DC screen was scorching.

Hello All, crazy stuff on this thread and tremendous work by everybody, insane amount of informations, so a big thank you first! 

Second, i'm very new (n00b) to modding, and i got a 8570w also (gift) since 2-3 years, and from what i read, we can do a lot of upgrade with this elitebook, and since day one, i really wanted to push this beast to a build with a lot of potential. For now, i just updated the stockage to a SSD kingston, replace the heatsink (the laptop was overheating everytime with slightiest use) by the a spare one, and still dealing with the original cpu and gpu (quadro k2000m). I will definitly upgrade the CPU with the Core i7-3940XM (pretty simple task) but then come the gpu part, and all the mods il will have to do. I saw that  @Daedalus had the same desire regarding his 8570w, did you manage to finally install a 980m on it ?
