Cool. I'm thinking just to go for the skylake though instead of broadwell. new=cool yolo, ideas for mobo? Broadwell was actually released after Skylake, only days ago. Making it the newest CPU, and the stronger one in games for the same price. Don't know about mobo for Skylake really, I got the Asus z170-a for mine but I don't overclock so you'll probably want to go for the pro version at least since you plan on doing that. Good luck with the build.
Thank you for your help

You need to remember that broadwell, while faster at stock due to the L4 cache, isn't nearly as capable of OC as either devil's canyon of skylake; broadwell basically goes up to 4.2-4.3 as well as DC at 4.6 or Skylake at 4.5
at equivalent OC's broadwell basically has the same graphical performance while suffering ~10% in CPU heavy workloads

because the strong point is in integrated graphics broadwell laptops are what should actually be looked forward to, the broadwell H series (most notably i5-5350H and i7 5750/5850HQ skews) may give us similar perf to a 850m in an integrated chip which would be amazing

I believe Skylake to be the superior option @OC's. There's no reason to throw an lga1150 platform + 4670k in the trash and buy a new PC build with broadwell. If you're getting a new CPU, just get Skylake. If you're getting broadwell (which i don't think is good) then you can just buy the CPU, GPU, maybe a PSU and nothing else and your upgrade is done.
broadwell basically goes up to 4.2-4.3 as well as DC at 4.6 or Skylake at 4.5
DC average is ~4.6@1.33 and Skylake is noticably at least a bit more consistent if not better as well at overclocking
The l4 cache on broadwell CPU is nice, but it lacks many skylake IPC gains, at least a few hundred mhz of OC (~4-5% performance) and skylake gets some performance gains from fast RAM too. I have not really seen any review comparing skylake @4.7ghz with ddr4 3200c16 to broadwell+L4 at 4.4ghz with 2400c10, though - only stock settings and slow RAM

I am a man of efficiency. The strong integrated gpu on broadwell is unnecessary and has a hefty premium with it. L4 cache is a result of that gpu too. It may be just a side effect that cpu gets increased performance from it.
Don't know about you guys but in my place price difference between i5 5675c and i5-4690K is a whopping ~%35 (300 vs 400 USD).

@Cyro, I dont disagree but my current pc is going to my younger brother who struggles with league of legends on his very old prebuilt HP (I once owned a similar one and feel his pain) and with my current economy i figured yolo. that's my reasoning behind throwing away haswell for a slightly better version ^^
|
if you're building a PC from scratch skylake is probably the better bet
though there are some pretty nice deals for mid tier haswell stuff like a 4590+z87mobo+8gram for like 250 in the US

That's fine in which case i'd recommend 6600k (or even 6700k)

Yep im going for the i7 one but still can't find a good mobo, right now im looking at gigabytes z170m-d3h because i have the z87 one and im ok with it. any good? also looking at the asus pro that he suggested earlier but i still have no idea. hard finding good reviews that i understand :D

I cannot, they conflict with other benches i saw.. Did they bench other games too? Wouldn't recommend 2133c15 for skylake though as that's like the 1066-1333 c9 of ddr3 when you can get much faster ram for same price and it matters more than ever

1280 x 720 at medium greatly favors the tiny but faster L4 cache on broadwell and is a usecase that does not actually exist in real life as nobody would every play those games at that resolution with a 980ti

^Is hard to say that. Those games are generally GPU bound titles so you do have to turn down resolution to show 150 vs 170fps, that's why it's better to test the CPU monsters like sc2, ksp, WoW, total war, ashes of the singularity and such which will be CPU bound hard without having to use a tiny resolution and reduced settings.

at 1920 x 1080 / high (still not a real usecase for a machine with those specs but whatever) the broadwell and skylake benchmarks are almost identical as previously noted:

refer to the benchmarks from the same article

Quoting my post because no one answered 
EDIT: Just saw Cyro's post about RAM, so I guess I should get something better there. Also just saw that DDR4-3000 e.g. would be not much more expensive.

You're completely right that it's not a real life situation, and nobody would play at these settings but I thought that in order to fairly judge CPU's you needed to go down to silly low settings in order to find out what wins when the GPU plays no part.
Their 1080p Ultra settings test obviously shows that there's no clear winner, but that doesn't really say much because his 4690k also scores pretty much identically in these tests. So when determined to buy a new CPU, specifically for games wouldn't you pick the one that's theoretically faster in these applications?

In settings in which GPU plays no part the broadwell processor is obviously superior, just refer to the integrated graphics benchmarks
however touting out 1280x720 medium benchmarks is purely to highlight a specific advantage of the broadwell platform due to its architecture. I'd imagine the advantage would be even more pronounced in say; Counterstrike 1.6 medium 800x600 where the entire game's VRAM usage would fit into the L4 cache but it doesn't make the benchmark relevant in reasonable realistic use cases.
Keep in mind that the identical at 1920x1080p is at stock and from other sources we can see that at 1080p OC'd skylake does, in fact, out perform broadwell; something this article chose to conveniently omit

basically broadwell gets smashed in CPU benchmarks, comes out even in 1080p benchmarks, and falls behind in 1440p and 4k benchmarks as a general trend. If you're gaming at sub 1080p, decide to omit a dedicated graphics card, or need to save 20W, broadwell is the choice - the only real use case for that would be in intel NUCs
