Motherboard: MSI Z170A Gaming M7
CPU : Intel i5 6600k @ 4.2GHz\
RAM : Patriot Viper DDR4 4GB x 2
PSU : Corsair 850w

I'm running two ASUS GTX 670s in SLI and when I run a game they typically sit at 50% GPU Usage but at a random time while in game GPU 2 starts to tank and drops down to as low as 0% usage while GPU climbs up to 95%+ usage. GPU 2 sits at around 20%.


I have made sure that SLI was enabled in the Nvidia control panel and switched Physx from Auto-select to GPU 2 (I've also tried setting it to GPU 1 but didn't really make a difference).

The GPUs both sit at around 55°C
