Milleniumtiger, what it means is that you will need 2 6-pin PCI-e power connectors from your PSU. It has nothing to do with 2 PCI-e slots. A 2 slot cooler means that the HSF on the card is so big that it takes up the space of a slot beneath the graphics card. In laymen's terms, the cooler on the card is as "high" as the HSF on the 7900GTX, or double as "high" as the HSF on the 7900GT. Clearer now?
