I'm looking at finally upgrading my m17x from its old 7970m to a 980m, but the person I contacted to buy the card from warned me that the 980m requires a 200W power supply, and win10 (I'm still on 7, but I can upgrade easily enough, so that shouldn't be too much of a problem).
I have read that the 7970m only required 100W, so I have no idea if my laptop would even be able to power the 980m or whether this would just be a waste of several hundred pounds. Can anyone clarify?
Also, I have read on here that installing a new card in an m17x require you to manually update the video drivers, but I'm afraid that I'm not quite sure what that means, exactly - would I need to rely on kindly users on here to keep uploading new modded versions of the video drivers in perpetuity, or is it just that I need to somehow tweak the installation on new drivers in future?
