How well does the PowerColor PCS+ AXR9 290X graphics card overclock? We were wondering the same thing and fired up AMD Catalyst Control Center to find out!
The APowerColor PCS+ AXR9 290X out of the box with the latest Catalyst 14.3 beta drviers scored 10,053 points in 3DMark Fire Strike.
After our overclock we were able to get a score of 10,764 3DMarks. This is 7% performance improvement and shows that you can still get some nice performance gains from an already factory overclocked card! You can use other utilities to increase the GPU core voltage to get this card to run even faster. This card is running 1.273V and if you bumped it up to 1.30 to 1.35V you can easily get 1200MHz stable and with some luck you can get 1225-1250MHz with stability.
