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.

AMD has released the official Catalyst 11.8 graphics driver.

New Features:

• AMD Overdrive has been enhanced to include both CPU and GPU over-clocking controls within the AMD Vision Control Center
• CPU over-clocking is only supported on AMD Black edition CPUs
• Performance Improvements: 10% in Crysis 2 DX11, 8% in Fear 3 DirectX 11, 20% in Call of Duty Black Operations and 30% when AMD’s Morphological Anti-Aliasing (MLAA) is enabled through the Catalyst™ Control Center
  

Of special note is that the 11.8 drivers brings support for 5x1 Eyefinity back into a release driver. Many users have been stuck at 10.12 or 11.4 Preview. 5x1 users can now enjoy all the the performance improvements from recent releases.
