I spent about 6 hours yesterday screwing with settings, updating (in most cases already current) drivers, installing and reinstalling the client and all the tools/patches, checking and rechecking router and firewall settings, even using my phone as a hotspot to take out my internet connection from the equation.

Solution
Proc: AMD FX-9370 stock at 4.4 GHz, 8 cores.

Went into the BIOS, dropped the clock multiplier from 22X to 18X dropping the core speed down to 3.6 GHz.

Logged right in, played for about 11 hours straight, no problems.

Note: Software (AMD Overdrive) did not work for me, this had to be done in the BIOS.
