There's a volt-mod for these cards? I'm not great at soldering, but I'm interested to learn about the volt mod since these cards (at least mine) run VERY cool--I'd be willing to bet they have a lot of headroom. Even so, I'm still surprised how much the gpu OC's on stock volts!
Everybody get out and OC those 4670s
