I finally got around to running my benchmark suite with the HD 6970s installed. I get 24367 3DMarks
in 3DMark06 (up from 24274 with the HD 5970), P27012 3DMarks
in Vantage with CPU physics (up from P22925), and P33958 3DMarks
in Vantage with PPU physics.
As for Crysis (DirectX 10, 1080p, 4xAA, high spec with no motion blur), I get
64.52 FPS avg, 39.64 min at 9am (up from 60.05 / 29.79)
64.73 FPS avg, 39.73 min at 1pm (up from 60.29 / 35.11)
61.10 FPS avg, 40.36 min at 5pm (up from 56.92 / 34.01)
Several attempts to clock things any higher have failed. I am trying absolutely one last setting, and then I am calling it quits. If it passes, I guess I have to run my suite again.
All I am really waiting on to be completely done is for CPUz to update, so it stops showing my graphics card as an HD 5970 at an undefined speed.
