Here are my heaven bench runs with my XFX 5870. First result with default drivers: Result with 10.2 drivers I believe: Result with 10.3a drivers (had 4x AA for some reason): Result with 10.3a drivers and all maxed settings: Anyone have any idea why this is happening???? Everything is set the same in each run except for the different drivers. I am not sure why the CPU is showing up as running at 3.2GHz in a couple of the runs and then 3.8GHz in the others. It is OC'd to 3.8GHz and has been running stable for over a week. Also, the OC is prime95 and OCCT stable. Any thoughts? The 5870 is not overclocked. Stock GPU and memory clocks.
