ya , I think its the MSI system itself .... the 311.70 from MSI work so , well the 320.49 do work well except it bugs out sometimes when switching from igpu to dgpu but thats all, also the 780M OC vbios on MSI GPU with the MSI laptop doesn't allow the voltage to go above 1.012 , which i believe is the default max voltage if i am not wrong. it might just be that the NOS system they created might have a fixed voltage set for the Card on MB ... maybe i hope i am wrong

hello. I have almost exact gear and driver combination you've mentioned.

can be that gpus switching repaired somehow?

it annoys if you are listening music from notebook in backpack and suddenly battery are going to draw fast a there is 'suddenly' too hot in there ). And milions other situations.

Uninstall driver is absoletuly last resolution; performance boost is too significant.

thanx all

as 'xcskiier23' says, using overclocked y580 with unlocked bios(and custom cooling pad ) and games like Rage, Dishonored, Need4Speed, Deus Ex run surprisingly playable on mid to high details(well, it's 'only' lcd frame projection fps max, but it must be ready for every situation, when new areas are loading or in perforamce heavy momnet etc. - it will not drop fps).

my first though was to buy nb in similar price you are asking, but after a hour considerations, in these days, it comes one of the most.

wish you luck

one touch recovery(search under y580 lenovo software site - it's not bound to current model software) do the job including w8 compatibility

had recently byued a Razer Taipan. it's ambidexterious mouse and beware, the two buttons on the side is shared. perfectly precise mouse, but with my usb 2.0 there's a lag . so I changed it for Abyss. razers mose is the best so far I had in hands using models for almost decade now
