Hey guys. i have an m17xr4 and my 7970m just died. So i decided to get new gpu the nvidia 880m. Im new at opening this pc but ive opened previous models like the r2. What i need help with is stuff like which bios should i get, any special heatsink modification i should be aware about. Any link to a vid, thread or service manual will be helpful. i just want this transition to be as flawless as possible. Thank you and i greatly appreciate it. ![:)]( "Smile :)")
