Yes the i7-4790K is still a good CPU especially for gaming and especially if you already have a Z97. Be sure you get a good cooler with it, the stock cooler is not sufficient. I'd recommend at least Hyper 212 or Cryorig H7 or better.
Yeap, i have the hyper evo 212 right now, by saying is still good you mean it still handles pretty good compared to the new gen cpus at the same price?
Yes it is still good because it offers the same number of cores at nearly the same speed as a 6700K/7700 and can be overclocked to the same. The very small difference in Instructions Per Cycle makes it still a good CPU. I would consider buying a used one to save the cost, ~$250 on eBay right now.
Like WildCard999 said, 8th-gen should also be considered. The sweet spot for gaming in my opinion is the i5-8400. It performs slightly better than a stock 4790K for a lesser cost (not considering memory and motherboard.)
Intel doesn't have anything to do with the current cost of the 4790K because they no longer manufacture them. They shipped those out in the past when they were at full price. Now it's the retailers who control the price, and since they bought them from Intel or a whole-seller at full price that's what they sell them at unless they decide to do a special price sale.
