Now this was a little surprising, but as you can see, the card can overclock much MUCH higher and that has a very positive effect on overall performance. We did not apply any voltage tweaking here. Play around with that and you will pass the 750 MHz marker, no doubt, maybe even 800 MHz. 790 MHz on the core was really pushing it though, two MHz more and we'd get artifacts.
There's something else I want to mention here. I'm not saying you should, by all means no. But we already informed you that the PCB, packaging and GPU on both the GTX 465 and 470 are 100% similar. We flashed a GTX 470 BIOS in one of the GTX 465 cards just to see if it would work, and it ran perfectly fine. Risky yes .. the extra disabled shader clusters could be damaged. But well let's just say, keep this little story in mind.
