MultiGPU scaling investigated

AnandTech has taken another look at the scaling of multi-GPU solutions, you can check it out over here. The reporter tested the scalability of recent ATI and NVIDIA graphics cards in seven games and also took a look at the power consumption. This is the first part of a series of articles on multiGPU hardware on AnandTech, the next articles will focus on 3-way and 4-way solutions.
Over the past few weeks we've been benchmarking and analyzing lots of numbers. We've looked at single, two, three and four GPU systems across multiple games and resolutions. The configurations we chose to look at are current generation high-ish end hardware capable of operation in 3-way and 4-way configurations. Because of the sheer volume of data we collected, we've decided to break up our analysis into multiple articles.
One of the conclusions of the article is that multiple card solutions see a reduced value because you're getting less than linear scaling, and that in general, you only need more than one GPU if you're gaming on a 30" LCD display.
