It's not difficult at all. You just need to take out the heat pipe and fan, screw of the x-bracket and there you go, one more push to get the card out and replace the new one. There is a 980m replacement but you also need to upgrade the adapter as well.

Just wonder if the version of gtx 680m is the 2gb ver or 4gb ver. And if yes, is there any difference between them? I just flashed the vbios to an unlocked vbios in order to have higher clock.

By default, m17x r4 has two hard driver slots including the RAID cable, and one more if you disassemble the DVD dual slot and replace it with the combo caddy bay + hard driver.
