I was in your spot back trying to decide want console I wanted, and I ultimately decided to build a new PC first, and wait for things to develop further on the PS4 and XB1. I'd say save some more money and build a gaming PC... Seriously, more games, more options, and just more general usefullness. It's a customizable experience. It was a better decision for me personally. (Plus I needed a new computer soon anyways, as my laptop was having issues.) It sounds like you don't have any specific games that your really excited about for either console, so just sit back, and wait and see what comes in the future.
My argument is that neither option is worth getting atm.
