Please re-read the first line of his post -- he says 2500K at 4.5 GHz. Since the 2500K did not ship stock at anything close to that....

A year and change ago I moved from my trusty i5-2500K (at 4.4GHz) to the current i7-6700K and the smoothness improvement overall was massive, particularly in games. Just like posters above described, games where I had uneven framerates and/or hitching just became smooth as silk.
Back when I wrote about this in the forums, there was no small measure of incredulity as "in theory it wouldn't be a huge jump." Well, as it happens, 5-10% IPC generational improvements over some four (five?) generations do add up.

In applications with HTT/SMT support, the 8-core R7 1700 blitzes i7 7700K completely. i7 7700K has 30% higher clock speeds, but I think core-count and more threads make the 1700 a much better deal. Also, you can overclock the R7 1700 to 4Ghz, which is still shy from the 5GHz i7 7700K but it's absolutely great for an 8-core monster.

Really glad to hear that I'm not the only gerbil out there with a success story upgrading CPU from Sandy Bridge to current gen.
I wonder why the perception across the internet doesn't match the reality here. Does it have to do with the fact that these are multiplayer results, with no great way to reproduce?

It is particularly hard on them as Sandy Bridge was seen as a special beast (unicorn). They enjoyed their time in the sun and the current gen offers nothing out of the ordinary for them. They have to rejoin us mere mortals.

First of all, it's not that people think there is no benefit from upgrading, rather, up until Kabby, people just didn't think there was *enough* benefit to justify the cost. Secondly, opinion really did start to turn to "it is getting to be worth it" with the arrival of Kabby Lake, at least as far as I remember. TR's review of the 7700k said:This is OP.

That's a pretty balanced statement that suggests that Sandy Bridge is no longer good enough for people with powerful GPUs - at least when playing certain games.Many readers are likely wondering whether it's finally time to retire their Sandy Bridge or Ivy Bridge systems with the advent of Kaby Lake. If the Core i7-7700K's performance in productivity tasks doesn't tantalize you, perhaps its gaming performance will. With a blisteringly fast graphics card like the GeForce GTX 1080 installed, many of our more CPU-bound gaming tests at 1920x1080 show that older systems can limit the maximum performance one can achieve with today's highest-end graphics cards. That behavior isn't consistent across every game we tested, to be sure, but it does suggest that you might be leaving a lot of performance on the table if you just plop a GTX 1070 or GTX 1080 into a five-year-old PC.
