Now you can get multi-GPU workstation graphics goodness in one of those slim desktops, too. Nvidia has announced the Quadro NVS 420, a graphics card it claims to be "the industry's only low profile professional graphics solution designed for maximum display real estate with a small form factor computer."
The firm isn't kidding when it talks about display real estate, either. This small card can accommodate up to four 30" 2560x1600 displays thanks to a proprietary-looking connector at the back, which can apparently spider out into four dual-link DVI ports. Other than that, the official spec sheet advertises two GPUs each with 256MB of memory, a 64-bit memory interface, and 11.2GB/s of memory bandwidth. Nvidia specifies 16 stream processors for the entire card, as well.
Despite the two GPUs and the active cooling, the card has pretty reasonable power draw—just 40W at full load, Nvidia claims. Nevertheless, you'll have to cough up $499 for one of these babies when they hit the market next month.
