Was just watching that video not long ago. Sandy is still keeping up, overclocked paired with nice ram but even so Skylake do offer some nice ipc improvement over last gen CPU's.
You'll have to spend much on a unlocked Skylake CPU, decent MB and some fast ddr4 ram. If you ask me, isnt worth the upgrade atm.

I'll keep mine little longer, its still a little beast at 4.8Ghz.

Yep, we're talking quite a bit of money too.
I looked back at what I paid for the parts back in early 2012 and I'd get crap for the same amount today.

I'll do a complete system overhaul on my 2600K build when I see at minimum a 50% IPC increase when comparing Sandy Bridge to a future Intel chip.

If you all are so confident SB is enough, then I guess my HW is more then enough - well I know it is @ 4.7GHZ I see how it stacks against current scenario, wipes the floor with anything 4/8HT atm.

Im planing to stick with this until a see a proper entry 8core cpu anyway, e.g something on LGA2011 CannonLake+ or from AMD Zen+ in 2 or 3yrs+ time

Also a nice test, 2600k vs 6700k (GTX970). Is it the time to upgrade? No, not really :

Haha,nice vids,had a proper meditation earlier today if i should upgrade my cpu, while it can still hold it , i don't feel its enough for what i play(gw2) and i do get some nasty dips here and there.

If i had a 2600k that would be a different story, but it's not, and i decided it's time for me to upgrade, knowing myself, i wouldn't make it without upgrading till cannonlake/zen anyway ,so i guess the sooner the better. Decided to order a 6700k ,16gb of ddr4 and an asus ranger mobo. I should get a decent boost from what i have now.

Well I upgraded from a 2500k @ 4.4 Ghz to 5820k @ 4.4. In most games there isn't a big difference but games like Watch_Dogs, GTAV, Dying Light that utilize those cores I see 10 fps higher on average, with no dips in fps.

My 2500k was running 100% utilization(driving or moving fast) in those games while the 5820k goes around 30-70% useage.

6core 12threads on 5820k, ofc you'll see lower CPU usage and like you said, difference in average fps isnt that big but minimum tend to improve in CPU bound scenes.

Overclocking that 2500k further can reduce that as well. 4.4Ghz was fairly average for Sandy chip.

The only real justification for upgrading to Skylake from Sandy, is if you experience a hardware failure. Otherwise, it's not worth the cost for the majority of people.

Actually, upgrading has some benefits, a couple of months ago I was in the same decision.
Turns out that min FPS did suffer an improvement.

Overall the system does feel a tad snappier, so I guess it just depends on your needs, wallet or urge to upgrade.

Its not 50% plus performance by any means, but it does increase overall system performance.

I've not seen a single game max out my cpu. No where near need to upgrade it yet.

Onl benefit would be power usage and better threading if and when games finally catchup

Love those revisit videos. Besides WD2 (which likes multi-core CPU's) 2500k still performs very well. Real gains are shown with an overclock. Even an average Sandy chip can reach 4.5ghz+.

Still, time for an upgrade is getting close and im looking at you Ryzen.

I'm still using mine but I'm stuck with 2x2GB ram. I added 2 more sticks for 4x2GB. It was fine at first but after a few months I got a lot of crashes and BSODs. Turns out my mb didnt want 4 sticks anymore. I got no problems w/ 2 sticks.

I am kinda forced to upgrade to either Kaby or Zen cause I dont want to spend money on 2x4GB ddr3

Good to see the i5 are still going good at gaming for the most part. i7 looks great but in gaming i dont see paying the premium for 30% increase in fps. Plus i am stuck on lga1150 for a couple more years to get my money out of this new motherboard so yeah its nice to see the i5 going strong.

It's not that there isn't the realisation that the newer processors aren't faster, just that there hasn't really beeen a gain worthwhile apart from the inclusion of AVX2 etc. Apparently Intel are looking at a 'new' x86 instruction set. Most likely this will just be the removal of all non AVX etc instructions from the processor and any use of those instructions would be done by emulation. The soonest this will likely happen is with Ice Lake, the modified version of Cannonlake for desktop computers. It might not be until after Ice Lake though. The reason for doing this is it saves space on the chip.

Coffee Lake will likely be a bit of a boost over Kaby Lake as it isn't supposedly just a refresh, but I don't expect too much gain either. Cannonlake will still 'exist' in part with Ice Lake, so the performance of Coffee Lake would likely be less. However, Cannonlake will be used on low powered devices (it's the high frequencies that don't work with the architecture currently), so Coffee Lake would have to perform well against those. The six-core looks interesting, but again the cost couldn't be so cheap as to devalue their enthusiast socket 2011 platform.

In the meantime, Zen will be getting a refresh next year (Zen+) with a 10 percent IPC gain, with the potential, as so far rumoured, to be going to a new process, for example 7 nm or 10 nm, in 2018 with further improvements (and updated socket, likely backwards compatible but most benefits with a new board), followed by another one with at least 10 percent IPC boost. This is important as Ice Lake will likely be going against this third gen Zen, which is rumoured to see at least 20 percent gain over release Zen, if not more, and not including the benefits of any additional instruction sets. The fourth gen Zen will release when Ice Lake is still around then competing against Tiger Lake (Ice Lake Refresh).

So basically, Zen is not only the most attractive, at least to me, option this year, but looking forward for at least 4 years due to the improvements already in the planning. Supposedly the Zen replacement is already on the drawing board, likely without native x86 code like future Intel's (unless they get rid of it sooner). There is also suggestion of future CPU's resembling, at least in part, to GPU's in terms of architecture and parellel processing.

In any case, the stagnation of tech is soon to come to an end with Zen, and also Vega GPU's (well, technically I guess the Nvidia GTX 10xx series and Radeon 4xx series was the beginning of this) which as some interesting architectural changes, such as how it utilises memory etc (an 8 GB Vega would be even more of an overkill for anything less than 4K).

So unfortunately for Intel the first 'worthy' upgrade is likely Coffee Lake, and if you're not Intel-only, Zen.

It's not all negative though. The money I would have spent on platform upgrades I instead could spent on GPUs...

Actually, I like that there's been no huge progress since Sandy. Good for my wallet :-P I have never in the past stayed on the same CPU for 6 years.

From that GamerNexus video, the 2500k, even at 4.5ghz is getting spanked by the 6600k/7600k most of the time. Time to upgrade indeed, waiting to see how Ryzen turns out. Not getting my hopes up though.

Why is that? Try to push it more. My reaches 4.7 easy with 1.38v and i can use it at 4.8ghz but it needs 1.4v+.

Btw, eclap highly overclocked 2500k + fast ram isnt getting spanked by stock 6600/7600k. Its more or less have similiar performance.
