GeForce Announcement

Nvidia GeForce will not let AMD stealing all the attention. They show that by advertising an event at GDC on the same day as AMD already announced their event on Ryzen and Vega.

Because if you go to GeForce.com you'll meet a countdown, counting down 6 days, which is the same day as AMD's announcement.

It is expected that Nvidia will announce their upcoming GPU, namely the new high-end card GTX 1080Ti. The reason to think that's what going to happen is that the 'Ti' in Time on the countdown page is highlighted in bold. So it strongly suggests that this is what is going to happen.

It has so far only been guesswork on what to is coming and what specifications the card gets, and Nvidia has kept the cards fairly close.
