Gainward Phantom GTX570 Review
The always gorgeous, and equally harsh on performance, Unigine Heaven benchmark gives the Phantom just about the edge in performance over its reference counterpart. Both are way behind the HD6970 which AMD confess has been tuned to be great at exactly those things Unigine stresses.
Even with the image quality levels bumped right up both GTX570s keep apace with each other nicely. The HD6970 stretches its lead even further, but 47 FPS with everything up to the stops is impressive enough.
