Smart Doctor, and it's truly dreadful. MSI Afterburner should allow voltage mods for it too though if you're lucky. It certainly worked with the EVGA GTX 460 I've been playing with.
GTX460 is pretty much the only card worth overclocking at the moment. bump to 470 performance for free.
i tried overclocking with my 5870, a couple unnoticeable FPS more for a lot of work and possibility of instability. don't know about you, i don't think it's worth it.

Find a different bios for your GPU and flash it to a bios that isnt voltage locked. Personally I wouldnt touch the voltage. I have my GPU overclocked through the bios by editing the bios with Nibitor and flashed the edited bios to my GPU and then tested it again. I first done the OC with software before doing it through the bios to make sure it was stable. My OC'd GTX280 is going strong with two years now and I dont have to run software to OC my GPU whenever I need to reinstall windows.

Was going to say the exact same thing. I just use RivaTuner for my 8800gts 640 (I know, needs to be upgraded) and I've found it to be a great program.

People that have dared flash a custom bios and overvolted further have got the core clock above 1100Ghz! Not sure how stable that is tho.
Never tried doing OC on my HD5870, it's already doomed, as she's stuck with the Q6600@3.2Ghz... And in the first reviews of the card, I never saw much benefit in fps, with the OC, it seems that the card is at it's maximum... maybe the 256bits bus has something to do with it...
Yeah, I used to experiment with OC'ing on my 8800GTX, then would flash it to the BIOS once I knew it was stable, as I don't like running apps in the background.
What I don't like with tools like MSI AfterBurner, is that everytime you start Windows, you need to give them Admin privileges. While the sucky (but still kinda works) Nvidia nTunes, doesn't (it's more of a problem with the editor, it does apply the settings correctly though). Also, nTunes provides almost the same features as the option tools.
what are the best over-clocking cards on the market?
also - I want an nvidia (as I have 3d ok!) card say 30-40% more powerful than the stock 460 - would an overclocked 470 reach that? can 480 even overclock?

I'd say go with 460 SLI as that's about 90% more powerful than one 460 and the same price as one 480 but again quite a bit more performance than one 480.
* Determine your current performance Run a test to determine how fast your PC is before overclocking.
* Get a benchmark Whether synthetic or real-world, get a benchmark that allows you to stress your overclock and give you an idea of how much speed you’re adding. You can use FRAPS and play a section of a game, use an in-game benchmark or download a synthetic test such as 3DMark Vantage or Unigine Heaven.
* Get your overclocking toolkit Download an overclocking application and GPU-Z to verify that it’s working.
* Raise the frequencies gradually, testing as you go You should be able to add something like 100MHz to the Core frequency of a good card, and 100-200MHz to the memory speed. Remember that after applying every overclock you need to run your chosen benchmark a few times to check that it’s stable, and that it’s actually increasing the performance of your PC.
* Bragging Once you’re done, and you’ve added 20 per cent more speed for free, you can officially boast your l33t skills to your friends and family. But don’t go on about it too much, or you’ll become Tech Support Guy/Girl for the rest of your life.

to my knowledge, rivatuner still has issues with newer graphics cards Nvidia GTX4xx cards are concerned, it might just be certain vendors and models, but i can verify that it does not work with my gtx460 whatsoever, so this may have had something to do with its exclusion from this guide.
worth mentioning is the fact that MSI Afterburner software actually is a heavily modified, reskinned build of RivaTuner with the most important functions brought to the front instead of hidden away (also worth mentioning, it -does- work with my card, where rivatuner itself does not).
otherwise i agree with you whole heartedly. rivatuner is teh sex indeed, it just might be a bit overwhelming for people getting their feet wet with gpu overclocking.
[my card is the Gigabyte GTX460 768mb @ 850mhz core/1700mhz shader - 4ghz vmem]
If overclocking a gpu puts you from a minimum of 22 fps to a playable minimum of 25 fps then it's worth it, otherwise if you have good fps then I wouldn't bother your just introducing instability for nothing.

Don't forget with overclocking you may be able to add more AA, shadows, effects etc whereas before OC you may have had to limit the special effects or resolution to make it playable. :)
But I agree there's little point overclocking it if you can play everything on max settings at stock speeds but I doubt most people will be able to max everything with newer games at high resolutions without at least a little overclocking.

try this good.. you can load in all your trusted apps at login using the task scheduler in vista/w7

Cool thanks.
But, another thing, is that at idle state of my computer I don't want my GPU overclock, and I don't want to switch by hand profile (and I know it's broken (like always) in nTunes this system).
Quick tip, advise people that if they have a card with a non-ref PCB that they may not be able to overvolt.
Like my card -.-
Although i did manage to get a 75 mhz core and 200 mhz memory oc.

yeah afterburner has a 2d and 3d profile built in- you can have different clocks on the desk than in 3d (set automatically).. the osd is nice too- allows you to turn off detection of certain games to run the more conservative clocks if you want.. not as nice as rivatuner, but not as bloated so I still use it
the guy who wrote it actually openly calls people who use his app (precision and afterburner) noobs xD.. it's actually a really nice program though- I load in precision to set clocks first, then kill it with a script and afterburner is run (this gets by the apply oc at startup if your not using 2d/3d profiles)
