I would wait a little, it isn't outdated but it is about to be replaced by the X99 chipset soon, which will have DDR4 ram and support the i7 5xxxk series CPU's as well as 4xxxk series CPU's, Wait for that titan motherboard.
Z87 is much more modern, it has more USB 3.0 outputs and SATA 6GB/s outputs, which can be said it is greater on features, but LGA 2011 supports 40 lanes of bandwidth, whilst LGA 1150 only supports 28, making multi-GPU configuration much better on a X79/LGA 2011 System.
