Can I have some opinions on what build to go with based in my situation?

[johnnsti08]

Sorry for the length, but I'm getting a bit frustrated and was hoping for a second opinion. I am planning a new build, mainly for flight simulator which is heavy could bound, so I'm centering it around an i7. The other main purpose of this build is longevity (wont be upgrading or changing parts till one stops working.)

I'm also plan to run this on the cheapest 1440p monitor I could find and trying to choose between a GTX 1070 and 1080 (the 1080 for longevity for years to come without dropping settings). Went with the 6700k and z170 mobocracy because the difference in price between a 7700k and the cheapest z270 mobo is $50 and didn't think it was worth it. No SSD HDD or Windows required. Which build to go with? I could probably afford all 4 but I'm at a lost if the price differences are worth it as the less I could pay the better

This is my dream build really (looks good, functional, GTX 1080), but a bit more than I'll ideally want to pay, so I'm considering if it's worth it

Would Ryzen based be an option? FLight simiulators can rip threads yo

 

[geofelt]

I would definitely go with the i7-7700K option if it is only $50 more.
7700K is some 10% faster in passmark rating. $50 is a nit for your budget, particularly for the long term.
Then, 7700k will usually oc higher.
As of 1/13/17
What percent can get an overclock at a somewhat sane 1.4v Vcore.

I7-7700K
4.9 74%
5.0 56%
5.1 26%
5.2 5%

I7-6700K
4.9 5%
4.8 21%
4.7 64%
4.6 96%

I would stick with the NZXT case which has provision for two front 120/140 mm intakes.
Buy two 140mm fans fro the front to provide your parts with plenty of fresh air.
If all your cooling intake comes in from one place and is filtered, your parts will stay clean.

CM hyper212 should do the job, but is not the easiest to mount.
Look for a scythe kotetsu which cools better for $35 or so.
Here is a review http://www.silentpcreview.com/Scythe_Kotetsu

Since your budget can be pushed to include a GTX1080, buy one.
If you settle for a GTX1070, you will forever wonder if you made the right decision.

I think not.
My limited tests with FSX on a i5-7600K shows it to be more single thread oriented.
Many threads can be used to load textures concurrently, but I wonder how important that is to performance.

 

[0ldsch00l]

How old is the game engine? Its single threaded?!?!?!

 

[geofelt]

How old is the game engine? Its single threaded?!?!?!

FSX is some 15 years old.
It has had patches to improve multitasking over the years.
I use it on occasion, but can not claim to be an expert.
All multithreaded apps have some dependency on a fast master thread.
Read up on Amdahls law to see why many threads have limitations.

[johnnsti08]

I can't seem the quote on mobile, but yes geofelt is right, it's single threaded due to poor coding when it came out years ago, but new versions are trying to rectify it but it's still nowhere good enough. So CPUs with high ipc are essential sadly

 

[0ldsch00l]

Ahh the old MS flight sim? You mean they didnt update it like new game engines? JEez to me thats like quake just getting updates for 20 years lol. I mean like realease a new version with new DX12 game engine

 

[johnnsti08]

Thanks geo for the suggestion, I'll try to see if I could make some more compromises somewhere to fit them in
