NVIDIA's GeForce 6 SLI: Demolishing Performance Barriers

Danhill · Nov 24, 2004, 10:22 AM

NVIDIA’s Scalable Link Interface (SLI) is based on the simple principle of symmetric distribution of load, meaning that the architecture depends on (and will only really work) if both GPUs get the exact same load as one another. The nature of NVIDIA’s SLI indicates that odd combinations such as cards with different clock speeds or GPU feature sets (e.g. 16-pipes + 8 pipes) will not work; NVIDIA’s driver will run all cards at the lowest common clock speed, but there’s nothing you can do about trying to get different GPUs to work in SLI mode, the driver simply won’t let you enable the option.

"1600 x 1200 with 4X AA/8X AF enabled however there were some areas where even two 6800 Ultras would get choppy. But most resolutions and settings that were not smooth before on a single card were definitely playable thanks to SLI. "

Um, doesn't he know about the stutter bug in HL2? it probably isn't the cards at all- but the game needing a patch.
