Micro-Stuttering And GPU Scaling In CrossFire And SLI

Tom's Hardware has published an extremely detailed article investigating the issue of micro-stuttering and GPU scaling when using a multi-GPU configuration. This article gives an in depth look into micro-stuttering on twin, triple and quad GPU setups, and also examines any differences between CrossFire and SLI in regards to micro-stuttering.

The article also has a good number of comparison charts that show the current scaling differences between a number of single and multi card configurations.
