If you ever wanted a video card that rivaled your desktop for the amount of memory it has, Nvidia has just the ticket for you. The company has recently released their Quadro 5800 card
, which comes stock with an impressive 4GB of memory and is supposed to have upwards of 102GB/s of memory bandwidth available to it.
The massive card is intended for ultra-powerful workstations that could actually justify such large amounts of RAM, like in the CAD and Engineering fields, and comes with an ultra-powerful price at around $1500. That gets you essentially a GT200-based card with massive amounts of RAM that consumes up to 189W of power when in use.
These pricey cards compete with AMD's FireGL line, and the introduction of a 4GB unit gives them a selling point AMD currently does not have.
