I Need Some CPU Advice: Skylake or Devils Canyon/Haswell

I am going to take advantage of nicrocenters sale ASAP. I5 6600k for $180? Hell yeah! Anyways that's about $300 with MOBO and RAM, as they have a $30 off intel motherboards. BUT! I have an AMD FX CPU. I have ddr3 RAM. I really don't want to spend $70 on RAM, and not be able to use my current RAM. They also have a 4690k, for $190, but MOBO are cheaper and I can use existing RAM. My question is, say 3 years down the line, the 4690k starts to bottleneck. How hard will it be to find a 4770k? They are already not easy to find, and ar overpriced. What do you guys think? Sky lake or Devils Canyon? Also is the i3 7350k any good? Does it act like a quad core? I run flight sims and other CPU intensive games like GTA, and can it keep up?
 
i3 7350K makes no sense at current pricing. Unless you can get it at an absolute steal, you can cross that off the list straight away.

There's only maybe 10% clock for clock between Haswell and Skylake... and that's being generous really, so from a strictly performance standpoint you wouldn't want to pay much more for Skylake, and it certainly makes sense to save some money by reusing your DDR3 RAM if you can. The real bonuses to a Skylake build come from the platform. It has more PCIe lanes from the chipset for things like high speed storage or other high end devices. They tend to have bootable PCIe M.2 slots for NVMe boot drives, more USB3 and some have 3.1 Gen 2. If you don't care about those things then the Haswell i5 is probably a great pickup. But it's just something to bear in mind.

In my experience second hand Intel CPUs, particularly the high end OCable models, are rarely available for cheap on the second hand market. They tend either to be sold in a complete second hand build, and where they are available on their own they're often priced at or even sometimes above the price of the modern equivalent. Intel never seem interested in undermining the value of their current flagships by selling excess stock of last gen tech on the cheap. With the second-hand market, my suspicion is that loads of people look to upgrade from an i3 or i5 to the higher end chip. Given that it's very rare for a motherboard to fail, there's so few CPUs floating around that you get low supply + high demand = high (and sometimes ridiculous) pricing. I don't know whether that trend will continue into the future, but that's certainly been my experience trying to upgrade myself, as well as exploring the second hand market to help people out here on the forums.

My suggestion is you decide on either Haswell or Skylake based on whether the features of the Skylake build are worth the additional investment and new RAM.

I don't really have time to read rhysiam's post right now and I'll give you a short answer.
The i5-4690k will not start to bottleneck anytime soon, Haswell's IPC is maybe %10 worse than Skylake, so if 4690k starts to bottleneck, the 6600k will too.
