Hi,
I am baffled as to why my Gigabyte Radeon HD 6870 1GB OC Edition performs poorly when overclocked with AMD Overdrive (in Catalyst 11.8). The stock frequencies of this card are 915/4200 and I overclocked them to 925/4240 by using sliders. When running the benchmark in FarCry2 at MAX settings with its built in tool, I get a lower average and max FPS with overclocked frequencies. Temps are fine. Details below.
