Speaking of overclocking, that is another aspect that the PowerColor HD6950 PCS+ was able to shine in, the GPU clock speed. While it was unable to break the 1GHz clock speed, it did come damn close, ending up at 970MHz. While the GPU clock speed was able to get quite high, I was unable to push the memory speeds any further than 1330MHz, but when you look at a reference design HD6950, you are going to find 800MHz and 1250MHz as the stock speeds. Which means that over a reference design card, I actually ended up with a 21% overclock on the GPU and a 6% overclock on the memory, not too shabby.
