It has only been around two months since Nvidia launched the GTX Titan, its super-powerful, extremely efficient, very expensive graphics card.

However, new leaks reveal that Nvidia doesn't think the card brings enough to the table, and is working on two new models of Titan: a cheaper model, and an even faster one.
