So I have a pretty solid system, I think. Not too terribly savvy with this, but looking through Catalyst and other third party tracking software, It appears as though only one of the GPU's is active. Everything seems to be running at the same rate (FPS, Load times, etc.,) as my last computer, which was about 1/3 the computer this one is.

Is there a way to activate the second GPU or am I missing something entirely here?

Odds are you're missing something, but you've supplied pretty much no detail at all on which to base guesses.

Install MSI Afterburner to monitor GPU usage, which will let you know if both are being used in any particular fullscreen game (note that Crossfire does not work in windowed mode).

Does that include Fullscreen Borderless/Fullscreen Windowed?

 

I installed Afterburner and am still getting reports of no activity from GPU 2 except the fan running at 20% power. Temp remains at 0 along with usage.

A borderless window is still a window.  Crossfire works only with fullscreen games.
