In June, Nvidia released their 10 series cards. Starting with the 1080, then a few weeks later the 1070 and 1060. These have been the largest technology leap in video proformance since 2004 with the release of the GeForce 6 series cards (The tech that introduced bump mapping, which made walls look like they had texture). Take a look at the reviews from Anandtech.
These cards are in short supply and I have constant back orders, but they are trickling in. If your running anything lower then a 900 series card, now is the time to upgrade!
