Neo4j is a very good option.

ArangoDB is free open source multi model no-sql db that has decent¹ perfomance with graph support:

Depends on what kind of data and graph you are going to store/use. Neo4j is quite popular, cypher isn't very hard to learn, and it has lots of examples. Might be a good choice for a beginner.

Cayley is a good option; we use it in production.

Oh but I love a challenge. Are there reasons to choose cypher besides a gentle learning curve?

Yes. I love the Tinkerpop stack (http://tinkerpop.incubator.apache.org). I am currently writing a Python library as I develop an application around it called gizmo (https://github.com/emehrkay/gizmo).

"The performance will suffer if the dataset is much bigger than the memory."

That is a huge drawback when compared to relational databases.

A good follow-up question would be: which open-source graph databases can reasonably import and store graph data that's not small -- that is, more data than fits in than RAM? Without proprietary extensions?

In the rdf space there are a whole bunch. Graph as in sparkling gives you : Virtuoso Blazegraph Jena Rdf4j Ruby.rdf

There are more but these are opensource and I know them. And money more commercial ones.
