I know it doesn´t really matter how the job gets done, but I sort of expected more from the 4 CPU monster. And besides, they don´t have the same "gas mileage", the V56K needed an external PS only for the card.
Actually it doesn't need a external PS. They made it with an external powersupply to allow for the installation in to a broader range of systems. There are AGP specs that provide for 50% more power than the V5 6000 needs. IF something gets the job done, I don't care.
