Update: I think I hit a brick wall or pole, what have you.
GPU Clock: 945Mhz - Hit 950, and I start seeing pixels.
Memory Clock: 1350Mhz - Hit 1355, and I get a blank screen, non responsive.
FPS: 55 average
Temps: 74C MAX
I found the above out doing just a few minutes of FurMark. I'll do longer runs tomorrow, see if it's stable.
