I was having this same problem recently when I was feeding a spyder with two HD outputs (1920 x 1200) for the left and right of a blended widescreen and we observed latency between the halves as well. In this scenario, we butted the two hard edge signals up side by side in the spyder which looked great other than the latency on fast moving video. Our servers are the new MAC pros with 2GB RAM, 128GB SSD, and X1900XT Video.

In considering future projects, I think that the Tripple head is an interesting potential solution but I am concerned that we'll be a bit limited in resolution as well.
