As soon as I close down trackIR the clock speed drops and the cards become idle.
This was not the case pre-upgrade/format with the 340 drivers and 2 670 cards.
Thankfully the 980's take less power then the 670's but its still wasted power
I'm running trackIR 5.2.2 build 14548 on Win7Sp1 64bit.
Nvidia driver is version 344.48 which is the new 'game ready' marketing thing driver they have going.
