Quote from blackdogDoes it?? 970M or 980M?
Ah yes! This reminds me! I had a bit of an issue with my screen, and after a string of cock-ups by Gigabyte and their supporting partners they replaced the entire laptop. Same model, but the revised version has a 970M instead of the 870M.
Bonus get!
Regarding the potential overheating, you can always mess with the power profiles to avoid increased battery consumption and heat.
