Nice, was wondering when a GTA4 bench would pop up...

But this is the absolute limit of this card, with voltage you should be able to go past 1000mhz in 5870 with a stock cooler. There's no way you are raising the voltage of GTX 480 with stock cooler.
Neither of mine (I had one that I RMA'd, and one I kept) could top 910-920 for everyday gaming without issue (hours of continuous gaming, or without overclocking-related artifacts), even with voltage tweaked. Getting it stable meant making it run too hot even with the fan speed up a lot. They could make it for quick benches but that's it.
