Does the NV-78 turn my GPU into a two-slot card, or does it remain a single-slot card? One would argue that I'm wasting my money on a full-coverage block, but the MAZE 4 block takes up two slots and is fuck ugly. I'm getting a DFI LANPARTY SLI-DR mobo soon, want to go SLI, so I need the two PCI slots for an X-Fi and an 802.11g card.
