ATI and NVIDIA put lots of effort in promoting CrossFire and SLI but according to a survey by X-bit Labs, only a small minority of computer enthusiasts use more than one graphics card.
The majority of users (54%) use single-GPU configuration according to their needs, but not necessarily high-end graphics processing units (GPUs). Another huge group of people (31%) use utilize high-end graphics cards, those, which usually cost $299 and beyond. Those two groups represent 85% of computer enthusiasts, the main auditory of X-bit labs.
About 5% of computer users have two high-end graphics boards in their PCs from ATI or Nvidia with the majority of them using graphics cards powered by Nvidia GeForce 6800 Ultra GPUs or higher-speed options from the Santa Clara, California-based chip designer. Another 54 people (or roughly 2%) out of 2500 questioned used a pair of mainstream or low-end graphics cards in SLI or CrossFire multi-GPU mode.
But multi-GPU technologies may have higher market share in the future, as 7% of respondents plan to acquire a multi-GPU setup as time goes by and those technologies become more mature or affordable.
