Summary: The only reason I did not give this unit 5 stars is due to the fact that booting into OSX Mavericks 10.9.1 frequently resulted in 800x600 resolution instead of the monitor native and those settings were missing in the display preferences.
Summary: This is a good card to upgrade my system, but read the reviews first. This card is wider than most and it fits awkwardly in my Lian Li case. The card does not fit well in the case, but it works.
Summary: Cant complain especially this purchase was the first high end video card I got in years. The software that comes with it makes, overclocking it a breeze. Also this card can handle 4 monitor screens, dont need a second one!
Summary: So far OS X Mountain Lion feels snappy but I have not seen a big performance boost like I was anticipating in CS6 or 3D software on a Mac Pro Early 2009. I wonder if Apple or if the software developers out there are going to tap into its power since it's a bit of a niche product.
Summary: If you're shopping for this you probably know more about it than I do (or did, anyway), but I will affirm that the performance is amazing, at least coming from a GeForce4800+. The only downside is that the card is -even- longer than my old one.
Summary: I love NVidia, and have for some years. This is a great overall card, there are only a few minor complaints. Going from a GTX 460, to the 680 wasn't as serious a jump in performance as I thought it would be.
