Hey guys, just installed my Gigabyte 7970 last night and slowly started to OC it, what's the limit for voltage on these cards, 1.3V?

Guys, I see you're talking about the Power Limit... I understand how on stress-test programs it works and how it throttles them, but how can I see if throttles my FPS on BF3, for instance?

I've 3 different oc profiles. 1000Mhz - 1.075V ~ 1050Mhz - 1.112V and 1100Mhz - 1.149V. I mostly use the first one, the 'lighter', but I never increase the Power Limit. I leave it to 0%. Are there any solid indications for throttling while gaming?

For reference, my old 6950 idled at 49C with the fan running at 75%. Huge improvement. Very happy so far!

Put powertune to +20% immediately. It has shown to give better fps even if you run the card at stock. It just handles the load better.
Keep it at +20. Move the volts as you overclock.

Oh snap! How on earth did you test yours? Did you get that 7970 bios working then? Got the same cards and I've been watching your posts on the subject intently. Did I miss something?

You can tell by watching your clocks and voltage in game. If you trip the powertune limit, it throttle the card, and that implies all the things that come with throttling. If you overclock, you should definitely raise powertune.
