Diamond Viper V770 Ultra Review
In almost all cases, the Viper V770 Ultra's increase in frames per second was substantial when compared to the Viper V550, especially at higher resolutions (refer to the yellow, red, and green bars in the charts below).  In 32-bit color the increase was even greater.
To recap the benchmarks, the following charts indicate the percent increase in frames per second of the V770 Ultra over the V550 in all resolutions for most of the benchmarks.
For example, looking at the first chart (GLQuake 16-bit color timedemos), indicates that at a resolution of 1280x1024 (red bar) running the Bigass1 demo with the V770 Ultra overclocked (last column, Bigass1-O) results in over a 100% increase in frames per second over the V550.
