Instead of the usual two boards associated with SLI, it is infact a single slot solution. Gigabyte has also splurged on memory - instead of the default 1000 Mhz clock speed on memory, they have raised it to a whopping 1120 Mhz. The 3D1 will be bundled with Gigabyte's SLI solution with the MSRP set to 550$ so this will be an interesting alternative for gamers looking for both a card and board in one go.
