My opinion would be to go with the GTX 970, even though a bunch of benchmarks do show the GTX 780TI beating the GTX 970 in 1080p res, its when you go to higher res screens like 1440p or even 4k that it shows that the GTX 970 can beat the GTX 780 TI. If you're like some people who like to buy 1 card now and then down the road buy another to SLI, then the GTX 970 makes more sense because in a few years time, 4K monitors could be the norm. So in that scenario, the GTX 970s would be a better solution.
