There's a total of 7 clock info modes listed in the BIOS (as opposed to 9 in the 4870). Idle is 157/300, and there's 850/1200 for full speed. There's also three other modes listed - 600/900 @ 1.063V, 400/900 @ 1.063V, and 400/1200 @ 1.063V. If I had to take a stab at guessing which they are, just based on what I know of the card and what I've read, 600/900 is throttling, 400/900 (labeled UVD) is for playback, and 400/1200 is for dual displays.
I don't actually use my computer for any high-def playback (I watch a regular DVD maybe once every two months), so I really can't comment on it's performance. Game-wise, it's amazing. The drivers still need work as I don't think the card is getting as much performance as it should be, but that'll come. I "side-stepped" over from my GTX295, and I have to say there's a marked improvement in gameplay quality, especially with "smoothness" and flow. The overclocking capabilities of such a new chip are also impressive, especially considering the ease of software voltage modification. I'm still tinkering around with voltages and capabilties, but at 950MHz, this card is insane. I imagine better samples that can get to 1000MHz 24/7 with minor voltage adjustments will quite amazing.
The MSI Afterburner program works on all brands, that'd be my guess (a big kudos to MSI).
