The Titan series of video cards from NVIDIA have always been about being the most powerful single GPU product out there. Today, they are tacking that to another level.
The NVIDIA GeForce GTX Titan Z has TWO Titan Black GPUs onboard for a whopping 5,760 CUDA Cores of processing power. 12GB of 7Gbps video memory is also on the card as well. Yeah, this card's made for pushing out graphics like no other.
That's why it's also priced at $2999, or more than some high end computers. If you need the horse power, then this card is it, no two ways about it. Pair this up with some 4K monitors and you'll be in graphics heaven.
