Hello Guys, I'm looking to upgrade from Haswell i5 4460 to something newer because I have the opportunity to upgrade in these months.I want to upgrade to something that will last as long as possible.I'm a diehard first person shooter gamer, I'm looking to get the highest fps and I ocassionally record gameplays.I render with Sony Vegas too but I'm not too concerned about the time it takes to render.So MOSTLY high fps and recording (not streaming, just recording with shadowplay etc.)
This is how I'm going to do things.
1. I'm gonna buy the motherboard soon (so I have to choose between Kaby and Coffee Lake.) Budget : 150 Euros
2. Prob going to get the RAM after 1 month and I need 16GB no doubt. Budget : 130-140 Euros.
3. Lastly after 2 or 3 months I am going to get the CPU because I wanna wait for Coffee lake i7 cpus to drop the cost and because CPUS are the most expensive. Budget : 350 Euros
I want the Pc to last as long as possible (I'm going to OC the CPU in the far future if it's needed), that's why I'm going with the latest generation, also I have a corsair vs550 80plus PSU do i need to upgrade that too with along with the other components?
I'm looking to buy i7 7700k(currently 300 Euros) or i7 8700k(Currently 430 Euros) or i7 8700(currently 340 Euros) CPUs. I have an MSI armor gtx 1060 6gb OC.
Games I play or I'm looking to play : BF1, COD WW2, DESTINY 2, BATTLEFRONT 2 etc. (1080p gaming ONLY). I'm stuck and I need your help!

As a practical issue I would suggest you buy the motherboard, CPU and RAM together as closely as possible. Simply because with your planned time table of purchasing you run the risk of finding out a component is faulty months after purchase.

(1) If you go with a Kaby Lake motherboard, then waiting for Coffee Lake CPU to drop in price makes no sense.

(2) 16GB RAM is the minimum for content creation as far as I'm concerned.

(3) I wouldn't expect prices for Intel CPUs to drop that much (unless you're comparing to over inflated prices). Your budget excludes the i7-8700k. Your desire to eventually overclock excludes the i7-8700. This leaves you with the i7-7700k.
This depends if the budgets you've outlined for each part is fixed. An overall budget would make things a lot more flexible in terms of choice.

How long any PC lasts is mainly determined by the software you use and will use. (My old PC got a bit useless because it couldn't do the things I wanted with a new piece of software.) Any of those CPUs should be good for a few years to come; I don't see game development changing too much immediately just because Intel have now gone beyond 4 cores for the mainstream.

If the PSU is still good, then there isn't an immediate need to upgrade. I would upgrade if it's been in use for years as a safety precaution, but that's just me.

For 'future proofing' though, I would lean towards the eighth gen i7s, making the assumption developers will finally take advantage of increased core counts. Should help with recording gameplay too.

As it is, I think you'll need to think a bit more about how you want to approach this purchasing decision.

1. If I get a Kaby Lake mobo, I will get the parts much faster then if I get the Coffee Lake mobo, just because the i7 7700k is already cheaper than the i7 8700k.
2. Present games and newer games demand/are going to demand more than 8GB of RAM, that's the reason I need 16GB.
3. Well you never know what can happen with prices, but you are mostly right.
When I say 'Last' I dont mean in terms of Hardware ''Stamina'' I mean not to stay behind the latest gens.I mean 'future proof' like you said.
And yes I think generally it's better to lean towards the eighth gen.My PSU is still good, no complaints about it and it's 1 and a half years old. :) Thank you for your suggestions dude
p.s : Do I lose that many fps If I get a 2600mhz RAM instead of a 3000+mhz RAM?

Corsair VS series PSUs are the lowest quality ones. Please upgrade that first to something decent like CXm, RMx or HXm.
Secondly, buying an i7 7700k is now pointless as i5 8600k is there which is cheaper, some 2-3% faster at gaming and significantly faster at content creation, so if you are planning to go with i7 7700k, better not.
The 8700k is again an awesome CPU, strictly for gaming POV, there is no reason to get an 8700k over 8600k. However if you are planning to do some content creation, 8700k is the better choice due to hyperthreading.

So I would suggest, try to get an 8600k and get a new PSU from what you save. Believe me, that Corsair VS PSU will someday sink down the hole along with your system.

I was thinking about the i5 8600k but I thought it wasn't worth it to upgrade to. Yea I know it's a low tier PSU. Do you think that it's better to get the i7 8700 and pay a little extra for a good PSU? or Do you think that it's not worth the extra money? (i5 8600k currently costs 275 Euros).

Edit : Well I guess we exclude i7 7700k too because i5 8600k is equivalent and cheaper.

If you are not planning to overclock, i7 8700 is by far the best choice as it also comes with a cooler. However I feel getting an unlocked chip is obviously a more future proof option. 8600k can easily overclock to 5 Ghz and a 5Ghz 8600k won't need an upgrade for atleast 5 years. On the other hand, a locked processor will last well for 3 years but after that you will start feeling the need of overclocking. But again, buying an 8600k means you will have to spend on a CPU cooler. Initially you can settle for a cheap cooler and once you feel the need to overclock, you can get an expensive cooler.
But whatever you do, upgrade your PSU ASAP. It's a must,

If your aim is future proofing, forget kaby lake. 6 core processor is what you need. So decide between 8700k and 8600k. If you are only gaming, get the 8600k otherwise get 8700k if you are doing content creation.

It depends on the balance of the system you're aiming for. Extra cores/threads will help with the recording aspect.

ATi RaDEoN makes a good point about the i5-8600k (and PSU). Two extra cores to help with content creation and Intel's IPC advantage. Given current supplies though, you will be looking at next year I think. I've heard people use 'paper launch' with respect to the eighth gen Intel CPUs due to limited stock.

Generally speaking, faster RAM speeds do help in some scenarios. From the benchmarks I'm aware of, it differs from game to game.

EDIT: I really need to type faster...

This is why I want to wait to purchase it last, choosing the CPU is the hardest for me. Furthermore if I get a chance to get 8700k at a lower price (350 Euros), I will defenitely buy it. I think it's worth the wait. You helped me a lot.

Haha it's okay.
About the Upgrade now. When I said I will buy the mobo soon, I mean that I wanna wait to see benchmarks and many many reviews of the 8th gen before buying the motherboard. Now I think 8th gen is a better choice because Ice Lake CPUS will also work on 300 series mobos. These are the best parts to get as 'future proof' as possible.

Okay so first I'm upgrading my PSU because it's really low quality. Then the mobo and ram. Lastly I will decide between the i7 8700 and the i5 8600k. :) I will try to buy the parts as closely as possible.

Another thing to consider, Intel is already talking Cannon lake next year, late next year I think. So who knows what upgrade options there will be even if you do go coffee lake.

If you are doing a lot of content creation, it's at least with tossing out the idea of the Ryzen 7 processors. For example for a little over 300 you could be into a Ryzen 7 1700 with 8 cores and 16 threads.

Gaming, your single core performance is on par with haswell, but if you are doing streaming and a lot of heavy multitasking or encoding, I'm guessing the Ryzen would slaughter that i5. And all the Ryzen chips can be overclocked.

Just saying with what it sounds like you are spending and what you appear to use your system for, it's worth considering.

However, you say streaming isn't as important as fps. So the i5 or the kaby i7 might be a better way to go, as I'm guessing you'd see similar fps with Ryzen as your haswell cpu.

I have considered Intel's move for Cannon Lake and I'm sure about upgrading to Cofffee Lake as Cannon Lake will be compatible with Coffee Lake mobos (300 series). The only reason I didnt pick Ryzen 7 1700x is because I care more about single core performance than multithreading or content creation. Thanks for answering even though I picked a solution, appreciate it.

Not a problem. I will say however, they may use the same socket as Coffee when Cannon comes out, not sure on that. However, Coffee uses the same socket as Kaby, and those aren't interchangeable. In fact I don't think you can even put a Kaby into a Coffee board.

But either way, I'm sure the Coffee Lake build will serve you well.

Yep they are not backwards compatible. However Kaby is in the same family as SkyLake (The only difference was the bios update that 100 series boards require to be compatible with Kaby Lake processors. Coffee is not at the same family with these two (obviously) and will probably be side to side with Cannon (2 in each family). However even if it's not I think I'm good with Coffee for many years to come (due to OCing the i5 8600k) as you said.
