Benchmark Results: 3DMark 11 And Crysis 2
3DMark scales linearly with clock rates here. Although there’s a definite relationship between frequency and performance, the difference between the fastest overclocked model and reference isn’t as significant as the price spread.
Crysis 2 demonstrates a spread similar to 3DMark 11. The degree of overclocking applies has less effect as the resolution increases, which is, unfortunately, the opposite of what someone buying a high-end card would want to see.
