I don't think 65 is a measly grade at all. Well, I hope not because that was my average for my UCL MSc. My supervisors at UCL did not consider 65 a measly grade by any means, nor did my current PhD supervisors!
Also, I was told that my career was over when I graduated with a 2.2, but it hasn't stopped me from obtaining 2 MScs (from UCL), a PhD studentship and publications-so I hope that would be some comfort for you
