Hi to everyone, I'm sorry if my question has been already answered but couldn't find it through the thread. I have an XMG P17SM based upon clevo P177SM bios 4.6.5 with amd 8970m. I would like to know if: 1) Is it possible to upgrade the gpu to a 880m or, even better, to a 980m? 2) Eventually do i just need to flash the bios with the last prema mod bios (v2)? 3) Is It enough to buy just the gpu or do i need to buy a new cooling fan and heatsink? In other words will my actually heatsink fit the 880 o 980? Many thanks for your answers
