I have just installed a new graphics card to accompany my old Galax (reference build) GTX 970: a Gigabyte Windforce GTX970. They work very well together, and they both get to 1400MHz (OC) with a normal SLI sync when benchmarking.
The problem is, however, that even though the Gigabyte card is called GPU1 and it's installed in the top slot, the Galax card, called GPU2, is the primary GPU. HDMI/DP cables will only work when inserted into the GPU2, and the GPU2 is the card that boots. GPU1 only turns on when its image processing power is required for heavy games and benchmarks and such. Otherwise it sits idle at 135Mhz.
I want GPU1 to be the primary GPU, because it has a better cooler, it's quieter, and because it has more ports. How can I change the primary GPU?
