4K video requires a computer with a lot of processing horsepower for editing. It also requires far more disc storage than you probably have now.
Unless you're involved in indie filmmaking or maybe commercial videography, spending money on 4K is probably not the best investment right now. That statement may become inoperative in 18 months, but, as one fellow said to me, when Wal-mart says they're going to sell 4K TVs that's when you want to get into 4K.
By the way, there is no broadcast spec for 4K and no plans for one either, so 4K will be an online or recorded medium for the foreseeable future.
