I think this card will really shine once non-reference PCBs come out that address the VRM and power issues that currently hinder this card from achieving higher clocks. I could be wrong, though.
The 7950GX2, 9800GX2, and GTX295 never received non-reference PCBs. Some AIBs released cards that came with waterblocks, but the PCB remained unchanged.
The GTX295 received an official PCB change from dual-PCB to single PCB, but that was for the cost savings. Software voltage control was removed for it.
