Also, note that while 760 Mars is faster compared to the 970, it is SLI and consumes quite a bit of power. SLI scaling isn't the same in all games, some are good with scaling and some won't scale at all and then there are SLI compatibility issues for some games. Since the 760 Mars only performs just a bit better, it's more ideal to get the GTX 970 since a single powerful card is usually better than getting two weaker cards that combine together to get slightly better performance for some games.
