PhysX Technology

NVIDIA® PhysX™ is the next big thing in gaming! Delivering physics in games is no easy task. It's an extremely compute-intensive environment based on a unique set of physics algorithms that require tremendous amounts of simultaneous mathematical and logical calculations. The best way to get real-time physics, such as explosions that cause dust and debris, characters with life-like motion, or cloth that drapes and tears naturally, is with an NVIDIA® PhysX™-ready GeForce® processor. PhysX software is widely adopted by over 150 games, is loved by more than 10,000 registered users, and is supported on Sony Playstation 3, Microsoft Xbox 360, Nintendo Wii and PCs. PhysX™ technology will take your gaming to a whole new level.


CUDA Technology

NVIDIA® CUDA™ technology unlocks the power of the hundreds of cores in your NVIDIA® GeForce® graphics processor (GPU) to accelerate some of the most performance hungry computing applications. CUDA™ technology is already adopted by thousands of programers to speed up those performance hungry computing applications.


SLI™ Technology

Delivers up to twice the performance of a single GPU configuration for unparalleled gaming experiences by allowing two graphics cards to run in parallel. A must-have feature for performance PCI Express graphics, the SLI dramatically improves performance on 60 top PC games.


NVIDIA® 3D Vision™

NVIDIA® 3D Vision™ brings a fully immersive stereoscopic 3D experience to the PC. A combination of high-tech wireless glasses and advanced software 3D Vision transforms hundreds of PC games into full stereoscopic 3D. You can even watch 3D movies and view 3D digital photographs in crystal-clear quality.


Microsoft Windows 7

Microsoft Windows 7 is a next-generation operating system that will mark a dramatic improvement in the way the OS takes advantage of the graphics processing unit (GPU) to provide a more compelling experience. By taking advantage of the GPU for both graphics and computing, Windows 7 will not only make today's PCs more visual and more interactive but also ensure that they have the speed and responsiveness customers crave.

5 out of 5 eggsTotally in Love

Pros: I plugged it in, updated my drivers, and it was off like a shot. Plays all my games on their highest settings, runs all 4 of my monitors no problem, and I never see any problems.

Cons: None that I have experienced.

Other Thoughts: My case is a bit small for this monster card, but that's not the cards fault. :)

5 out of 5 eggsExactly as advertised

Pros: I purchased this as an upgrade from an nVidia GTS 450, so I noticed immediate improvements across virtually every metric or benchmark. It runs every game I've thrown at it so far on at least "high" settings with 35+ fps. To be honest, though, on some games I had to turn down one or two settings to "medium" in order to keep that performance. But for a "mid-tier", ~$200 card that's exactly what I was expecting.

The card itself, appearance-wise, is fearsome. It looks like it belongs behind the grille of a car, cooling an engine. No fancy casing, no lighting... just two huge fans, a huge radiator, and some serious copper tubing. Despite that, it is super quiet - my computer case sits about two feet from me and is uncovered, and I only notice this card during more intense gaming.. not any different than other cards I've used.

Cons: The Overclocking software provided by Gigabyte isn't the best written software on the planet, but honestly I see no real reason to overclock in the first place so it's really a non-issue. I'm not real up-to-date on my technology, but apparently this GPU has a built-in boost (literally called "GPU Boost") that increases clock speed on demand, making a third-party program necessary only for the most extreme overclocking.

Other Thoughts: I can mine altcoins at around 170kh/s, and the card never got over 55 degrees celsius.

3 out of 5 eggsgood card

Pros: pretty fast,does high or ultra on most games at good frame rate,the power requirements are also fairly good.

Cons: Could be faster for the price considering I could have gotten an AMD gpu that is faster for 70$ less then what I payed for this.Also Nvidia needs to drop their prices a bit they are trying to be like what Intel is to AMD,where Intel charges big money for great performance and AMD charges a lot less for slower performing cpu's.The problem is Nvidia is not outperforming the AMD cards that are cheaper,and in a lot of cases an AMD card will be a lot faster then a Nvidia card and the Nvidia card will be ridiculously higher.And I understand Gigabyte made this card but for some reason Nvidia cards are always higher then comparable AMD cards.

Other Thoughts: price,performance ratio not good

5 out of 5 eggsExcellent Card for the Price

Pros: This card was exceptionally easy to install into the machine. Came with rubber/plastic covers over all connectors and ports to prevent dust and damage. Looks good, too. My gaming experience has been limited so far, but played SR4 on all high/ultra at around 60 fps. It had a few dips during heavy usage, but overall very good.

Cons: The driver installation CD provided was woefully outdated, containing 314.xx nvidia drivers while the latest is 335.23. Coming from a GT 630, some thorough cleaning and reinstallation took place. The fan farthest from the ports also obscured one of my SATA ports, but it was hooked up to the front ESATA port, so no big loss there.

Other Thoughts: So far, so good.

5 out of 5 eggsWorks wonders

Pros: Simple and the graphics are just wonderful. Had no issues installing.

Cons: a little ugly compared to the other 660 graphics cards, but i guess that's why it's a bit cheaper.

Other Thoughts: Overall? buy it. save that 20 dollars for NOT buying an evga 660 and buy CPU fan or save up for a water cooling. Will update in half a year.

5 out of 5 eggsFantastic

Pros: Works great. Easy to install and update drivers.

Cons: Had some difficulty managing its size with my other PCI cards.

Other Thoughts: Able to handle all of the newest and intense games on the highest graphics settings available in these games. Games tested so far (all on high or ultra-high)
