I don't know. It looks fake to me. Every picture i've seen looks like someone used HORRIBLE spray paint on both the heatsink as well as the PCI Bracket.
The heatsink pics look like it's all chipped and damaged on the edges and the card itself just doesn't look polished. What did this guy do, go picking through the dumpsters at the NVIDIA labs?
Anyway... real or fake... the ATI R600's "leaked specs" are much more impressive... I'll wait until Feb.
