Asus' Geforce GTX 4x0 cards to have Voltage Tweak
 

According to the pictures that can be found at Chinese site gb.financenews.sina.com, it looks like that Asus will stick to its Voltage Tweak even with the upcoming Nvidia Fermi GTX 480 and GTX 470 cards.

The pictured boxes are pretty standard and there has been rumours that Nvidia will give some voltage tweaking freedom once the GTX 480 and 470 are finally out. Even with those rumours, there was no talk on how high will those voltage tweaks go, but Asus' "up to 50 percent faster" claims suggest that more voltage might make Fermi quite faster.
