NVIDIA has now added a Quadro FX 4500 X2 to its lineup of professional graphics cards. While NVIDIA does not explicitly mention Quad SLI in the product announcement, the card sports a dual-GPU PCB strikingly similar to that of GeForce 7 Quad SLI cards, and NVIDIA says SLI support is on the menu along with "the industry's first quad dual-link DVI."

The new FX 4500 X2 also features 512MB of memory per GPU, a 256-bit memory bus, and 33.6GB/s of memory bandwidth. DailyTech claim the FX 4500 X2 draws over 200W at peak load, which would add up to an impressive 400W for a Quad SLI configuration. It is not known whether NVIDIA opted to build the Quadro X2 off a power-efficient 90nm G71-based GPU, though, or whether it's still made with the same 110nm G70-based GPU as the vanilla FX 4500.
