I don't have a source to link, but I can be a little more specific about the things I've heard from multiple owners. The famous revision 2B (i.e. the one that can be overclocked) does not scale resolutions and that the 2C revision that came afterward added the ability to scale from 720p. Referring to the DVI-only versions in both cases.
I haven't really payed attention to whether there are any differences in the later revisions. If they have all maintained the same capabilities as the 2C, then you probably have a pretty good probability of getting that, as most sellers are charging a large premium for the 2B models. However, I wouldn't put it past them to switch to a new revision at any time that changed the scaling capabilities, since the DVI-only models do not generally advertise that they have that feature.

Some of them have scalars, others don't. Another problem is controller lag,
This link is useful for getting the basics about the different models, but it could really stand to be updated. It was written in April, and some things have changed since then, particularly in relation to being able to buy overclocking models and the US companies like Auria, Nixeus, and Overlord.
