So a long time later, the new machine is running.
First off, the 7600K Kaby Lake couldn't be run by my BIOS, because the MOBO was 1 month too old to have gotten a factory update to run Kaby Lake. No CPU means no BIOS update, so it had to go into a shop where they performed the update at a very cheap and fast rate.
Realtek Audio Drivers can go die in a hole. As can the onboard sound card on my MOBO, which according to various descriptions isn't working correctly due to BIOS.
Also my old laptop's wifi card decided to KAPUT, which to me is a sign that it is on its way out quicker than expected. This ended my plans to bridge the connection through my laptop wifi before I move out.
So, I purchased a TP-LINK USB wifi adapter, which is working wonderfully and i rather enjoy. And second, an ASUS Sound Card, PCI-Express, which with a short update, is working perfectly AND driving my front panel audio ports. Apply money to fix problems? Yes, but I don't have the patience to wait for MSI to poop out a BIOS update anytime soon.
The journey is finished, I can now run Crysis on Ultra (or Vic Viper CFG mode).
