Some dialects pronounce /ɣ/ and /x/ the same (both voiceless), while in others, they're different. See w:Dutch phonology.

With "graag gedaan" there's also another change. "graag" ends with /x/ and "gedaan" begins with /ɣ/. When these two sounds come together, assimilation occurs which leaves only /x/.

Oh, I had not considered varieties.. And I wanted an online dictionary with phonetic transcription actually. Thank you anyways. Yeah, I passed Phonetics and Phonology in the last two terms! ;p

You can't really have a phonetic transcription without specifying which area. Dutch phonetics can differ quite a bit depending on where you are. For example, what is [oː] in one place might be [əʊ] in another.
