Asus Radeon EAH 5870 1GB Video Card Review
 

Aside from cost and availability there is little to differentiate one Radeon 5870 from another.

Asus is aiming to change that by offering a feature unique to its own brand of cards – the ability to tweak the GPU voltage without a need for hardware modification. Today we are going to be evaluating the card’s overall capabilities and testing to see just how much of an advantage this unique “Voltage Tweak” feature provides when overclocking."
