There's some very good information on this thread. I too am considering my next flight-sim PC, which will be accorded a fairly generous budget. All and any advice here is gratefully received.

Me too - about to drop quite a bit of money (in preparation of going from FSX to P3D V.4) and certainly, from my own research - and the wise owls here - the indicators are strongly in favour of a hefty L3 Cache - so that should be included in the primary focus of choice of CPU acquisition.

The 24.75Mb 7980 has 4.75Mb more L3 than the 20Mb 5960. Getting more cores is fine but remember that allocating memory bandwidth to more cores plays a part - the 7980 supports quad channel.

So does 7900X

If the motherboard is getting old maybe think about saving for a little while longer and get a new one at the same time?

The budget for the processor is  600 euros.

I have 1100 total for CPU , Memory and Mobo .

 

As I use a triple view setup with multiple cockpit suite modules running on this PC I need at least 6 cores. I prefer 8-10 cores. Unfortuntaly  the 7900 and above range is out of my limit if I also need to buy memory and mobo. 

I need to reinstall W10 within a short time as I found out that there where no big updates after 3-2017. Only small kb's. Microsoft has looked into my pc twice already and they could not fix it. Reimstall Windows 10 was the advice. So instead of summer 2018 I want to do a hardware upgrade now and reinstall W10.      

As I mentioned above, I have a triple view setup and therefore my maximum OC is Always 200-300 Mhz lower compared to a 1 monitor setup.

 

I am coming from a 5820K - 6 core --> 4.3 Ghz

 

8700K - 6 core  ( 12 mb L3 )   --> 4.7 GHz turbo --> 4.8-4.9 GHz man OC

7820x - 8 core  ( 11 mb L3 )   -->  4.3 GHz turbo --> 4.4-4.5 GHz man OC 

 

Suggestions ? Advice ?

What resulution ön monitors 3x1920/1080 ?

Did a test with 3x27inch 1920/1080 monitors,  can run the same cpu OC as with single monitor.

Not a big fan of the 7820x the 79xx series is better binned 

My 7980XE is delidded with CLU the cooling is a dedicated 420 rad för cpu, temps in p3d 55-60c  with ambient 20-22c at 5.0ghz on  all cores vcore 1.25v 

I prefer the 8700k before the 7820X think you can clock it 500-600mhz higher

Yes , 3x 1920x1080

I have tried to find a second hand 7900x ( new  € 900 ) )  for max  € 700 but was not able to find one. Not on esecond hand  7900x on the IN.

 

So it probably will become a 8700k.

 

 

Just stumbled across someone who is selling his 7940x with a Gigabyte Aorus X299 Gaming 7 mobo.

What do you guys think of this ?

Desirable. 

Just bought the 7940x and the mobo 

Now I have to buy 16 Gb of memory. A 16 Gb set of G Skill Trident 14 / 15 cl could be a good choice...

 

Good one!

G.Skill TridentZ Series DDR4 DIMM 16 GB - 2 x 8 GB 3600MHz ... 

With a 14 core processor icw P3Dv4 in triple view setup , is 16 Gb enough ? I do not want to spent on 32 Gb if it adds no extra.

So long as you fill enough slots for supporting quad channel. Not sure if it helps that much but at least 32 makes sure of things, 64 would be overkill.

I have read that quad channel is merely a 2-3% faster than dual channel but its price is at least 10-15% higher ..,

Increase in cost can only be due to needing more slots filled since you already paid for the chipset. 3% is that per core?

The 3% is measured by benchmarktests I have read. Same processor , same mobo. Same type of memory : only 4x4 ( as quad channel vs 2x8 as dual channel ).

Well I'd go for it. What about the M.2 slots? I would set up a raid system which I think would require two M.2's and an Optane to enable IRST services I need to look into it.
