This article has what I'm looking for:http://www.tomshardware.com/reviews/p67-gaming-3-way-sli-three-card-crossfire,2910-16.html
The timing couldn't have been better. Sandy bridge processors and the P67 chipset are great, but an overall increase of 2% using Sandy Bridge and one of the most expensive motherboards available for that chipset compared to a 1366 at higher resolutions is not enough for me to consider it an upgrade.
I'll build another 1366 (since I have many of these parts laying around as a result of upgrades) as a DAW and wait for the end of the year's architecture updates which are supposed to really step up the performance.
Additionally, I like Intel, but I'm really hoping the Dozer release will make some waves. After all, competition is good for us consumers.
