Nordic Hardware published a photo of the ASUS ROG ARES PCB, this is an upcoming dual Radeon HD 5870 graphics card with 4GB GDDR5
ASUS had the following to say:
"The whole PCB will be covered by a copper heat spreader that connects with the memory ICs. The power circuits will each be cooled by a individual copper profile. All thermal profiles (heat sinks) will be anodized black to create true ROG aesthetics in black and red."
The card will ship with Volterra voltage regulators for both GPU and memory, which enables users to change voltages through software. That is if you're one of the lucky few to get a hold of ASUS ROG Ares.
