Testing notes
Nvidia cards tend to run faster than the GPU Boost frequencies quoted in parentheses. For example, the Palit card averaged a core speed of 1,255MHz across the six real-world games, up from the 1,202MHz quoted on the literature. Bear this little nugget of information in mind when analysing results.
