Nvidia's newest graphics card is not for everyone. In fact, it will cost $3000. But, CEO Jen-Hsun Huang would argue that it's a terrific deal, given that it's about 50 cents per processor.
The GeForce GTX Titan Z includes two Kepler GPUs, totaling 5,760 processing cores, and 12GB of dedicated frame buffer memory. According to Nvidia, it's "engineered for next-generation 5K and multi-monitor gaming." It may be a bit of overkill for everyday use.
"If you're in desperate need of a supercomputer that you need to fit under your desk, we have just the card for you," Jen-Hsun said during the announcement.
