My build today is an i7 3770k @ 4.5Ghz + 16gb HyperX 1866mhz and GTX 1080 TI.

I'm between i7 7700k or Ryzen 7 (any, but maybe 1800X).

Usually my builds last about 3 years, except the GPU that I change every year, I was suppose to upgrade everything last year but waited because of all this launches.

Am I going to see much difference between this two builds?
I see Gigabyte k7 supports 3600mhz memory, I found the G.Skill kit: F4-3600C16D-16GTZR but didn't find any information if it is supported or not.

Most of the contents posted are for 1080p and that's bad for me that need to see comparison for my resolution, even regular 1440p is not accurate.

Any thoughts, opinions, materials, benchmarks to share and help this decision?
Also, do you guys think for long term investiment Ryzen 7 is the best option, now that AMD got back 20% of the market, game companies will start to develop better support for higher core count like the move from 32bits to 64bits?

Thanks in advance!

At 1440p, for gaming, an overclocked Ryzen R7 draws level with the i7 7700k. At stock speed, it'll be just behind - www.techspot.com/review/1348-amd-ryzen-gaming-performance/

Look at your preferred motherboard Memory QVL to find what memory is supported.

Interesting article, but it's comparing stock clocks, the thing is... 7700k @ 5Ghz and R7 1800X @ 4Ghz.

Do you know any material related to it?

The R7 1800x runs at 3.6 to 4.0 GHz without OC. The i7 runs at 4.2 to 4.5.

It would be an unbalanced test to run the i7 against the r7 with only one OC'd.

If you only want to game, then get the i7. If you also want to do content creation/multi-threaded applications (eg streaming) then get the r7.

Edit - found this - i7 5930k OC vs R7 1700 OC 1080p, 1440p and 4k gaming

Right, like I said most content show stock speeds or only one OC'ed.

Mainly this pc will be gaming, but if the next batch of games come with multi core optimization then R7 is a better buy right.

You said the right word there: IF.
If the software/games is making good use of those cores, yes, then Ryzen would pull ahead. But if the past years have told us anything, it's that optimisation on games is pretty much uncertain. I wouldn't relly on it (well, not for the next 1-2 Years).

now that AMD got back 20% of the market,
They haven't. That number came together, because more AMD chips were tested with Passmark (a Benchmark Software) - which makes sense, because AMD has just launched them, so there'll be more people testing them then for example an i7-7700k, because we pretty much know what it's capable of. It's also a small group of people using that software - the majority of users (like folks that just go into a shop and buy an OEM Dell, HP, etc., or companies and serverfarms) don't run passmark - hence, why these numbers don't reflect the real world. Their market-share Improvement was more along the line of 1% (if at all). It takes Years to get them and Ryzen has only just launched.

I see Gigabyte k7 supports 3600mhz memory

OC3D just released a video/article where they retested Ryzen. TTL mentioned that while Memory-Support has improved a lot, it can still be a bit difficult to get to 3200 or beyond.

He talks about that at around 12:20
youtu.be/wMPpdOaF0r4

The 3600 (as you posted) might be good/possible in the future, after a couple of updates - but as it stands right now, it might not be worth investing in better ram as you might end up having to run them on lower settings.

game companies will start to develop better support for higher core count like the move from 32bits to 64bits
They moved to 64bit because Windows moved - and because it's bad if a game uses 6 or 8 GB of ram when then the OS/engine can only support 4 GB. Moving to 64bit was pretty much a necessity, whereas optimizing a game for 8 instead of 4 cores is not. Besides, a lot of games (and other software) still depend more on IPC then on Thread-/Core-Count.

Am I going to see much difference between this two builds?

At 1440 Ultrawide (i.e. 3440x1440), the GPU will be the bottleneck and the difference between ryzen vs i7 will be minimal. You can see that when comparing 1080p vs 1440p vs 4k benchmarks: The higher the resolution, the smaller the gap between CPUs, because the overall performance is then dictated by the slowest component - the GPU.

Unless one choice is significantly cheaper then the other (for example, a discount, a sale, or something like that), it's up to personal taste. The i7 is slightly faster now, whereas an r7 might be faster tommorrow. It's up to you, which you think is the better proposition.

I still think that the 3770K @4.5 is still suitable for a gaming cpu. I run a 3570 @4.2 with a 1080ti. 7680X1440. Gpu bound all the way. At 2560x1440 I do not think you would gain more than 7-10 fps going to a new cpu.

$300cpu (cooler) +250 mobo + 200 ram = $750. A lot for 7-12 fps.

Now if you need it for productivity, streaming, rendering, etc it may be worth it. Just gaming I would hang on for another year.

I look at it this way- Would you upgrade a GPU for $750 to get 7-10 fps more? I would not. Since I have a 3570 non k @ 4.2 I am thinking of a new machine but I am not sure of the gains I would see. I would love to see 2k and 4k benches with older CPU's vs new ones in gaming.
