Have AMD drivers been better as of late? My experience with them, though it's been a couple years or so, was a lot of frustration.

Yah assuming you arent running Linux

 

That is not what the 80+ certification means.

 

A PSU that is 80+ certified simply means the PSU will be at least 80% efficient at 20%, 50%, and 100% load.

 

What you just said doesn't make any sense at all. You will never burn out a PSU by NOT stressing it. While your PSU is a bit less efficient when your computer is not drawing too much power (like when it's idle), BUT it only draws as much power as it needs thus making the low load efficiency argument pretty much irrelevant.

Also you would want to buy a higher wattage PSU not because more watts=better but they are more likely to not have problems down the road. Capacity degrade is a factor that lowers the amount of power that is able to be used. 

 

But yah the efficiency argument is not a great now, best PSU site (imo) is Johnny Guru

Despite All these controversial comments about the wattage of power supplies, I read somewhere that Geforce 760-770 need 700~800W PSUs. Is it correct?

Only if you want two of them.

A GTX 760 takes about 170W which would need it needs approximately 15A on the 12V line. Which you will probably find on anything above a 400W so I would say no. But generally since PSUs are generally not understood fully people say you need that much.
