Conclusion: Nvidia's dual-GPU card, the GeForce GTX 590, is undoubtedly powerful. But while it's quieter than AMD's own double-barreled Radeon HD 6990, that card delivers better overall performance for the same price.
Pros: Excellent performance. Quieter, shorter than AMD's competing card. Can control three monitors with DVI connectors.
Cons: Expensive. Performance surpassed by competition. An energy hog under load. Requires two eight-pin power adapters, hefty PSU.
Conclusion: If we removed Far Cry 2 from the results, we would actually have the GTX 590 to be 2% slower than the Radeon HD 6990. It's also interesting to note that a vast majority of the GTX 590's losses were in DX11 titles: S.T.A.L.K.E.R.: Call of Pripyat (-15%), Metro 2033 (-20%), Battlefield Bad Company 2 (-9%), and Aliens vs. Predator (-10%). Besides its 46.3% lead in Far Cry 2, the single GPU GTX 580 was also 22.5% faster than the HD 6990.
Conclusion: IMPORTANT: Although the rating and final score mentioned in this conclusion are made to be as objective as possible, please be advised that every author perceives these factors differently at various points in time. While we each do our best to ensure that all aspects of the product are considered, there are often times unforeseen market conditions and manufacturer changes which occur after publication that could render our rating obsolete.
Pros: Best total package for DX11 video games, Short profile fits into standard size computer cases, One card drives four displays or 3D Vision Surround, Fermi GPUs enable 3D Vision and PhysX functionality, Cooling fan operates at very quiet acoustic levels, Includes DisplayPort connectivity for future display tech, Supports quad-SLI for unmatched potential
Cons: Extremely expensive enthusiast product, Heated exhaust vents out to computer case, Does not include HDMI output for HDTVs
Excerpt: Over the years, we have consistently been impressed by cutting-edge dual-GPU powered graphics cards, not only for their relatively high performance, but because of the engineering involved to design, build, and bring the cards to market, in form factors not much bigger than their high-end, single-GPU based counterparts.
Pros: Extreme Performance, Relatively Quiet, PhysX and CUDA Support, Surround Gaming From One Card
Cons: Not As Fast As The 6990, Hefty Power Requirements, Pricey
Conclusion: When we were first shown the GTX 580 and 570 by NVIDIA it was clear that they had put some considerable focus on creating cards and GPUs which were offered better build quality and design than the previous generation. With the GTX 590 they have taken another step along that path, creating a dual GPU product which excels in the design and quality department.
ASUS NVIDIA GeForce GTX 590 graphics card reviewed and rated

Excerpt: Put on the kettle, make yourself comfortable, because you're about to find out which is the fastest graphics card in the world, dear reader. NVIDIA and AMD know all too well that the path to performance domination of the consumer PC graphics market can only be trod if two high-end GPUs are placed onto one board and set to communicate with one another via established multi-GPU technology.
Summary: Most folks seem to enjoy these value scatter plots, so let me drop one on you.
We've taken the results from the highest resolution or most intensive setting of each game tested, averaged them, and combined them with the lowest prevailing price at Newegg for each of these configurations. Doing so gives us a nice distribution of price-performance mixes, with the best tending toward the upper left and the worst toward the bottom right.
