NVIDIA's new Titan X was launched in the last few hours, and while it's priced at a wallet-busting $1200 - it has already sold out on NVIDIA's website.
NVIDIA's GeForce.com website is the only place in the world where you can buy the Titan X graphics card on its own, and I've just checked the site to get some detailed specifications for my own review (which is coming as fast as my fingers can type) - and it is listed as "Out of stock".
The new Titan X is a monster of a graphics card, with 12GB of GDDR5X (up from the 8GB on the GTX 1080) and a nice bump in performance over the impressive GTX 1080. We'll have some content on it flowing in the next few days, but considering they're already sold out - I'm blown away with the response so far.
