Pick whichever you want, OpenBSD will work fine. Of course, faster
models are still faster...

Do do some research on whether or not your preferred video encoding
application will use more than one core on OpenBSD; most won't,
especially as OpenBSD's current threading implementation does not permit
a threaded program to use more than one core. (Whereas e.g. Linux would
permit using one core per thread - this is not usually a problem, as
such workloads are not very common, but video encoding just might be one
of them.)

It's your own choice to either run two in parallel, or settle for the
fastest single-core processor you can find.
