I would personally get the msi r9 380 and I think it's is slightly more powerful but it would only be by a couple of fps so either card would be a good choice. Just go for whichever is cheapest or which you think is best looking.
yh that's what I was thinking I asked this question bescause I'm building a blue and black themed pc but the msi r9 is red and I don't really want to go for the red
