Get your game on with the GeForce GTX 770 Graphics Card. Featuring 2GB of GDDR5 vRAM coupled to 1536 CUDA cores with a 256-bit interface, the GTX 770 can render gameplay in HD and beyond HD resolutions at fast frame rates for smooth and consistent action. Not only good for gaming, the GTX 770's CUDA cores are arranged using NVIDIA's Kepler architecture. Compatible programs can leverage the parallel processing power of the GPU to accelerate compute-intensive software using the CUDA processing platform or APIs like OpenGL.
On the output panel of the card features four output ports; a DisplayPort terminal, an HDMI terminal, a dual-link DVI-D terminal, and a dual-link DVI-I terminal which supports VGA output via an optional DVI to VGA adapter. The HDMI and DisplayPort outputs support resolutions of up to 4096 x 2160. That resolution, combined with NVIDIA's Surround, can provide an immersive gaming experience using multiple monitors.
For cooling, the card has an integrated blower style cooling system. This system uses a radial fan at the intake to force cooler air from the case across the card's internal heatsink and out the exhaust vent at the front of the card. This type of cooling is advantageous in compact case configurations and SLI arrays because it does not recirculate air back into the case.
SLI Ready
With a compatible motherboard and a connecting bracket, up to four GPUs of the same model can combine processing power using NVIDIA's Scalable Link Interface (SLI). How the cards work together can be customized to suit your preferences. Alternate frame rendering has each alternating card prepare the next frame, essentially multiplying the capabilities of a single card's maximum capable frame rate output. Each card in the configuration can also be used to improve anti-aliasing by being able to process an image in parallel with the other cards before filtering out jagged edges.
Note: The benefits of SLI will differ based on CPU configuration.

DirectX 11
Launched in 2009, DirectX 11 opened up more advanced possibilities for improved NVIDIA graphic rendering techniques through advanced tessellation. Some of these techniques include:
- NVIDIA HairWorks - Allows for many thousands of individual hairs to be rendered and animated as opposed to earlier implementations of polygon strips and transparent textures.
- NVIDIA FaceWorks - Uses the additional tessellated detail provided by DirectX 11 to render faces with a more realistically round shape, with improved lighting to show contours.
- HBAO+ Ambient Occlusion - Adds more realistic shading and shadowing where two surfaces or objects meet. DirectX 11 allows for higher quality AO without creating a large performance hit.
- NVIDIA Percentage Closer Soft Shadows - Creates more realistic shadows by progressively blurring them relative to the distance of the object from the surface where the shadow is cast. The softening of the shadows also reduces aliasing which can be distracting.
- NVIDIA Crepuscular Rays - Also known as light rays, light shafts, or god rays, DirectX 11 renders these rays with tessellation rather than intensive ray-marching or viewspace slicing. This results in realistic imagery which has less impact on performance and graphics memory while simultaneously reducing aliasing.
- NVIDIA Depth of Field - Also known as NVDOF, increases precision and quality in cinematic depth-of-field effects by allowing the separation of the subject from the foreground and background. Highlights in the background can take on a polygonal character, similar to as if they had been captured with a real camera.
CUDA
NVIDIA's parallel computing platform which enables an increase in computing performance by harnessing the parallel nature of GPU processing. CUDA compatible applications can assign intensive parallel computing tasks, such as real-time video rendering, to the GPU to process, freeing up the computer's CPU to run other tasks.
3D Vision Support
When used with a 3D Vision compatible monitor and 3D Vision active-shutter glasses, full-HD resolution images are delivered to each eye. Additionally, with a 3D LightBoost compatible screen, image brightness will be maintained while using the glasses and ghosting will be reduced.
PhysX
NVIDIA's hardware accelerated physics engine computes how objects move in space in real time. Having a physics engine precludes the need for programs to pre-animate rendered objects which can give an unrealistic "canned animation" feel. The PhysX engine also allows for designers to create more detailed objects, relying on the GPU's processing power rather than a bloated programming back end.
TXAA
Temporal Anti-Aliasing is designed specifically to reduce temporal aliasing (crawling and flickering seen in motion when playing games). This technology is a mix of a temporal filter, hardware anti-aliasing, and custom computer generated film-style anti-aliasing resolves.
Adaptive V-Sync
NVIDIA's Adaptive Vertical Sync minimizes stuttering and tearing by monitoring and adjusting the card's frame rate output. At high frame rates, Adaptive V-Sync is enabled to slow down the output frame rate to prevent tearing as a result of losing sync with your monitor. At lower frame rates, Adaptive V-Sync will automatically be disabled to minimize stuttering.
GPU Boost 2.0
Boosts the card's clock speed in real time based on the target temperature. If the card is running below the set target temperature, GPU Boost 2.0 will increase the clock speed to improve performance. The target temperature can be reset depending on your preference so you can have the card run more quietly for everyday tasks and older games, and run at full tilt during intense high-resolution gaming sequences.
G-Sync
When used with a monitor that has G-Sync hardware installed, the monitor's refresh rate will sync and lock with the graphics card's output frame rate. Establishing this sync removes tearing and stuttering which can result from conventional fixed screen refresh rates, especially important for gaming in stereoscopic 3D. An additional benefit of G-Sync is reduced lag so gamers will benefit from the improved command response time as well.
4K
Display graphics, games, and video in UHD resolution (3840 x 2160) for increased detail on 4K resolution displays. Games which support 4K resolutions will display greater detail for enhanced realism and reduced artifacts. 4K video from services such as Netflix and YouTube can deliver full resolution video for an enhanced media experience.
Surround
With a single card you can expand your PC games across three displays in stereoscopic 3D for an "inside the game" experience. Add in a fourth accessory display to get access to your email, web, and other applications.
DSR
NVIDIA's Dynamic Super Resolution is a scaling utility introduced with their Maxwell architecture. DSR uses the GPU architecture in order to take advantage of 4K capabilities with lower screen resolutions by having the graphics card render at 4K and then intelligently down-sample the output to fit the smaller screen. Aliasing and jagged artifacts are reduced by having a high-quality filter applied before the image is scaled down.
