I'm deciding whether I should get the GTX 780 Poseidon or MSI GTX 970. In some cases the 970 performs better than the 780 in benchmarks, and vice versa with the 780. Also they say that the 780 has better overclocking potential which can outperform the GTX 970. What makes it really hard is that they're around the same price on Newegg. So which should I get?
