A software update (unsure if it's Windows 10 or not ?) caused major delays for the US Customs Airport Security that made long lines and delays happen for a couple of hours. They are investigating the incident as of this time and to make sure that this doesn't happen again.
Lol, okay since of your current situation that you can't get a new one, I would get the one with fewer cycles because it will last longer and either way the Macbook Air is usually has a long standby time.
Just get a brand new one because I don't like using used batteries to replace.

I have a low-end gaming computer and I am upgrading my video card from a R7 270 to possibly a GTX 1060 or RX 480.
Is the CPU able to handle those two or should I get something more cheaper and a "better" fit?
