Being Nvidia's top of the range single GPU card this card is expected to deliver.
Being a graphics card there are going to be only a few uses of this for people: High end gaming, 3D, and video editing/production.
Being somebody who dabbles in all 3 I can think of no better card at this price point.
With regard to games it offers premium quality, giving a large boost in FPS in all my games. Crysis is the usualy benchamark for such things and I was blown away with the cards ability to run it on my system.
The card makes light work of things such as 3Ds Max aswell, I have noticed a decent decrease in render time. Video editing also is helped by this card making the whole process a lot quicker.
The card is not without flaws however, for a start it's very expensive, but givin that it outclasses anything in this price range it is worth it. The 1GB DDR3 ram is definatley worth the extra money over the 275 as we see increasing screen resolutions.
Despite how much it costs I can highly reccomend this card for any enthusiasts.
