GeForce GTX 780 SLI Game Requirement Analysis
GeForce GTX 780 SLI is a combination of 2 GeForce GTX 780 put together using NVIDIA's SLI technology.
Together, this combination offers 4608 Shader Processing Units, 384 TMUs and 96 ROPs. This, on a 384-bit memory interface, per card, of fast GDDR5. While the central unit runs at 863MHz and goes up to 902MHz, in Turbo Mode, the memory clock operates at 1502MHz.
Best case scenario, this combination surpasses considerably a single GeForce GTX 690 but ultimately, its performance depends on the driver support and on the 3D application.
Therefore, and paired with a powerful processor, all demanding games are playable at the highest settings. Still, this combination might surpass the 500W barrier of TDP and so it will require a powerful PSU.
