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 ?
