From what I've heard, IPC isn't getting too big of a boost from Coffee Lake. This is me just spewing complete bs, and none of this is really confirmed, but it seems that Coffee Lake is a slightly modified Kaby Lake processor to allow slight IPC gains and implementation of 6c/12t CPUs. I know that Coffee Lake laptop CPUs are basically just rebranded Kaby Lake CPUs as well.
40-50% IPC gain seems pretty damn large, and I doubt that Coffee Lake will be that.
EDIT: In terms of gaming performance, Coffee Lake will obviously be better than Kaby Lake. What really matters is what games you play. If the games you play can use more than 4 cores, Coffee Lake will likely smash Kaby Lake into the dirt. However if the game doesn't, you may see similar performance to Kaby Lake (it may be better or worse - we'll see. If performance is as good as Kaby Lake or better it will still be a very good line of CPUs). Really Coffee Lake is a response to keep Ryzen 5/7 out of the market, and adding more cores appeals to more people (content creators coming into mind here).

The only huge jump in CPU performance Intel has produced that I can think of is the Core 2 Quad < Nehalem.
Nehalem was about 40-50% faster than the C2Q because of things like the integrated memory controller,
Since then, each generation of Core processor has made about a 5% increase in performance, but is much more energy-efficient.
If I'm building a 2-way SLI GTX 1080 gaming PC, should I hold out for the Coffee Lake, or should I go ahead now and buy the Kaby Lake?
Also, will Kaby Lake prices go down after coffee lake's launch?

Expect something like 5-10% performance increase from 7700K-8700K in games and that's it. Heavily multi-threaded applications, well that's another story.
The 40% increase is multithreaded applications, IPC is only a small boost. However the exciting cpu for me is the 8600k, a 6 core i5 with the same or better single core performance of the 7700k should compete with or even beat the 7700k. The hyperthreading of the 7700k only gives it at best a 30% increase over the 7600k so a 8600k with 50% more physical cores and claimed 40% improved multithreaded performance should be similar or even beat the 7700k. All this for an i5 price we hope.

By todays games, not by much as most games, with a few exceptions, are not using more than 4 threads. This may change in the future though.
Over the last 2 years (mostly 1 year) a few games have released that benefit from more than 4 threads and it seems to be a trend that is growing. For now the benefits are not great unless trying to push high fps in these games but 4 threads is quickly becoming the minimum standard. With Coffee Lake 4 core will now be the i3 range so Intel are also accepting it is no longer acceptable for a mid range CPU.

From everything I've seen thus far, we can expect a modest 10% - 15% gain in IPC, which is very likely coming from higher base / boost clocks, than any significant changes in the architecture. The advantage coffee lake will have is that they'll have more cores. Doesn't mean much for lightly threaded apps, but, as games continue to transition to using DX12 and the other new APIs, multi-threading will become more the norm.
6 core CPUs seem to be the sweet spot atm. Small enough core counts that they're not putting out a TON of heat, so they can still clock higher for increased single core performance, and enough threads that they'll still do well in heavily threaded tasks.
