For my new setup, my main prerequisite is **three 1920\*1200 monitors in portrait**.

I would preferably want to use them with a **laptop** though, so it seems my options are:

* Matrox TripleHead2Go  

But I don't really like the idea of having three monitors fused into one.
* 3 dedicated USB->DVI adapters  

Here I'm worried that the **USB bus will get clogged** resulting in degraded performance, especially since I'll need to resort to a **USB hub** in any case, to plug other devices in.

This setup would be used for working mostly with **text**, **no gaming**, but it would be a bummer if performance was so bad it couldn't decently play a video.

Does anyone know **what kind of performance can be expected from the USB adapters solution**?
