The world of high-end graphics workstations grew a bit this week, with Nvidia announcing a new piece of hardware for the Mac Pro line of machines. The Quadro FX 4800 has been introduced as a top of the line professional GPU, aimed at people working on animation, production and video processing. With a price tag up in the clouds at around $1,800, this card is no lightweight, costing nearly as much as a what Mac Pro itself would run you. That price gets you a many workstation-oriented features, including a massive 1.5GB frame buffer and 76.8GB/sec memory bandwidth.
Given that probably not a single one of these cards would ever be used in a gaming rig, Nvidia isn't playing up specs much. Interestingly, the press release makes it a point to indicate they are aiming this card at Mac Pro, specifically saying that it was designed around common software used in graphics development on the Mac.
