upgrade intel i7 4790k to Intel i7-7820X

Do you think, it's worth to upgrade from intel i7 4790k to Intel i7-7820X ?

For gaming only.

http://www.cpu-world.com/Compare/605/Intel_Core_i7_i7-4790K_vs_Intel_Core_i7_i7-7820X.html

How important is the L1 / L2 / L3 cache, for gaming ??

Any advices are welcome, thank you

That would be one very expensive upgrade.

The point is, would that be worth ?

No, I dare to say it would be a dramatic downgrade !

You will not be able to overclock that 7820 to a single core speed that could match your very fast 4-core 4790k if you also overclock that one.

Given how hard it is to cool the new i7's it would actually be foolish to think so.

Stick to what you have, overclock it and be happy that you outperform any new i7 in IPC with a FRACTION of the heat and power consumption involved to oc those new 4+ core i7's

If you want brutal performance for almost fair money, look my sig, that is maybe the last CPU Intel did only for gamers imho...and even that is nonsense with your CPU...stick to what you have and wait for better times..ehhm CPU's

I'd like to OC my CPU but i do play CoD also, and this flight sim doesen't like OC

How do you come to that conclusion ???

Many many Pilots in here are hardest core overclockers, YES ! DCS doenst mind to run on highly overclocked machines.

YOu should make sure your CPU is cooled properly and your overall sysconfig is STABLE while in OC MODE. You can run tests to find that out.

If you need a guide to do that, just gimme a beep :book:

wait for the 8700K I7 later this year, it will be faster than the 7820X for gaming and for less money.

Currently the 7820X scores the same in games as the AMD R7, but the later costs half. Take your pick.

I'll plan out my next Rig upgrade, once I see the VR Gen 2. I'm sure it'll have a HUGE requirement, both CPU/GPU.

To buy into the X299 platform for gaming only is pointless. If need to purchase now then go either for i7-7700k or cheaper i5-7600k from Intel. Even cheaper option would be AMD Ryzen 5 1600/1600x. Or if you can wait see what Intel release with Coffee Lake hex core CPU's later/end of this year hopefully. I know that is what I have been doing since the Ryzen releases earlier this year.

Plenty of reviews out there. Once below with loads on benchmarks:

Stick with the 4790k, its a formidable cpu, one of the best of all times. i have it and will have it for quite some time

Have you ever overclocked your CPU and then ran a few hourlong stresstests to verify it is stable ?

No program can sense if it runs on overclocked CPU`s...they use the CPU and it either works stable or it crashes from what I understand from overclocking.

Anyway,, keep that CPU, it's at 4.4GHz in TurboMode, there aint much to gain anyway unless you like overclocking personally.

Zero improvements in skylake-X from haswell and broadwell for gaming, even for multicore aware games:

UIGGSxHpuoE

Skylake X does overclock higher but then you have to tackle the monstrous heat output with very expensive cooling solutions. I dont think there are motherboards up to the task yet. those might come later.

This is a poor showing for Intel. Im so glad I went R7 from my 2500K and didnt wait for these I9's.

I would wait for Coffe lake, those promise more for gaming (6 cores 12 threads and a better suited L1/L2/L3 cache system). If you cant wait just go AMD (best CPU is 1600 right now) and use the savings to get a better graphics card.

Pilotasso have you had any issues with the motherboard you are using? I read some not flattering things about it.

Okay guys, thanks a lot, I'll keep the CPU

I just wanted to find a way to improve the FPS, for DCS, especially the Normandy map

What about to replace the GTX 1080 with 1080 Ti?

Or, i should better wait until 2018, when Volta arrives?

My OLD PC had the i5 4770 4Ghz Turbo max.

My new one is in my sig, tweaked with the help of the guys here, I would definitely even lightly OC that chip of yours for now Lenux, you will see good benefits.

I have an ASUS board so I run AI suite, this allows me to switch the overclock without leaving windows. Not sure if Gigabyte has something similar? Even if it doesn't, it must be able to save a bios setup or Profile?

That way you can save the settings you have now for other sims, not exactly sure why a sim would have a problem? Every sim I have would want more CPU if I could push it any further without melting the CPU.

and Like BIGNEWY said, the sim will get better when more optimized.

Also you are running DCS on a TV right, are you seeing lag here? I have tried DCS on My Sony BRAVIA and it does a half decent job in sim with it's built in Motionflow 200Hz, It's Still no where near my ASUS 144Hz 1ms. Dont expect it to be silky smooth like a Gsync monitor.

"The KS7500 is a good candidate for gaming, too. Its dedicated Games mode saw a response time of just 24ms in our tests, down from 117ms with the mode turned off. This is one of the fastest times I've seen, so console owners shouldn't have any problems playing fast-paced games here."

Have you got this "dedicated Games mode" turned on? It's still at 24ms! So don't expect lag free with all the power you throw at it, this could be why you think you need more power perhaps?

What setting are you running in DCS, turn down the Visibility to Ultra, I set this to high when testing very large missions, when using Deferred Shading, I turn off MSAA and Anisotropic Filter at the moment and set them in the NVIDIA Control panel.

.

OMG..24ms is it's fastest mode !

That is OK for Wold of Warships and stuff like that but maybe not what you should use for DCS that is highly depending on fast input processing.

You may want to test a buddies PC-Monitor with better values and see if that already delivers what you look for. For the cost of a new 5820 + mobo + RAM you can buy a real nice Gsync and say ADIOS to all those lag and stutter problems.

Gsync is beyond believe, you gotta see it to believe it, hands down !

I think, input lag has nothing to do with FPS

Yes, I'd go for a monitor, but it's not easy to go back, from 55 inches, to 27

By the way, i didn't notice the input lag with DCS

I don't play FPS games at all

Post your DCS settings,

I can max the sim out with my system and still hold 55 FPS Flying low, flat out through Vegas, F15 quick flight takeoff mission and I 'm only running the 1070, yes I have a newer system, CPU / Ram / mobo. Still I'm interested in what your getting with your system with the 1080 and 4790K.

What are your expectations? I have tested and found a balance/ compromise in the settings, especially if you setup larger battles.

Like I said in my earlier post, my TV is only OK, but has absolutely nothing on my G-SYNC, 144Hz, 1ms screen. You say you dont play first person shooters? DCS can be much much harder on screens than any first person shooter, how fast are you moving in a FPS game? Not 200 Knots or mach 1+ (767 Mph) most of the time.

Unless you only fly around at 20,000 feet? I like going real fast low with Viggen too, this is where my screen really comes into play, I can look very quickly sideways with Track IR at Mach 1 when flying at 100 feet.

That's what BitMaster means by highly depending on fast input processing.

Sorry for the late response. :]

The AMD motherboards have a lesser degree of automation in overclocking. Its is more of an old school hands on experience guessing trial and error. You have to control the parameters more directly (for example, memory sub-timings).

Rules of thumb:

1-Be mindfull what each timing does, if you feel you can't master it all leave those on auto.

2-Do overclocking by the book. Be methodical. otherwise you will be clueless if something goes wrong.

3-Be conservative, know where the hardware is hitting the limits and drop a notch (dont chase after the mythical 4Ghz barrier if voltages and temperatures are spiking)

4-Dont skinp on the PSU and choosing the right memory kits is paramount.

I frequented forums and saw people mistyping voltages, trying to flash Zipped files or are using the wrong type of memory for overclocking etc. Most have an Intel overclocking background and are spoiled by automation (example: memory XMP profiles).

90% of the people shouldn't be allowed to mess in there TBH. This is where most of the horror stories come from.

If you are uncomfortable with overclocking just go for a B350 board with a X CPU (1600X, 1800X)

I've had no problems whatsoever with the crosshair VI and each BIOS iteration has allowed me to up a notch on my overclocking and stability.

Also, if you buy Gskill RGB kits dont use RGB software from either ASUS or Gskill. Its a known source of memory corruption issues and the fix has not yet come about.

LED's are known to make your PC 7% faster !!!
