Overclocking and Overclocked Performance
I was actually really pleased with the overclock on this, a huge 153MHz over the stock boost speed to a huge 1457MHz.
3DMark Fire Strike
The overclock had an adverse effect on during the Firestrike benchmark, a small blip really.
When the stress is cranked up to 1440, the Phoenix 970 is nipping at the heels of the GTX 980.
Even at 4K, the Phoenix 970 is still performing well.
