SLI/Crossfire does NOT need x16 PCIE3 for full bandwidth. You can go all the way down to x4 3.0 with barely any difference. Pump it up to 3-GPUs then you might need x8. There's nothing that saturates x16 PCIE3 yet.

I'm on an SSD Still lags. Also AMD drivers are totally crap.
The easiest way to prove the CPU core thing is to uncheck all but two cores. You'll immediately see the two cores you didn't uncheck hit just a little over 50% and the rest will drop to near zero. That is how you know a game is only using one CPU core. I have yet to see a game functionally use more than two cores, and most of the time it's one core almost everything, while the second, third and fourth cores are running threads that don't take up more than 1% of the performance. Playing back audio hasn't been CPU intensive since 1999. The game should push physics off onto other cores (since that's something that actually benefits from it) but nope, it's not doing that either.
