Hi, I was contemplating upgrade from my 3 year old now i2700k to i4790K and wanted to see if anyone did something similar and is it worth it in terms of performance increase mainly P3D, since ver 2.3 of P3D came out FSX is going off my drive for good.

 

I also use a 2gb gtx680 and was thinking of staying with it, maybe if p3d comes out with SLI i pick up another one...

 

I am mostly interested in anyone's experience as to this CPU upgrade going from i2700k to i4790, even in case of FSX performance.

 

currently i run the i2700k at 4.5Ghz, it was going at 4.9Ghz but i updated bios and forgot what all my setting were LOL i4790 would also by OC'd a bit.

 

I would be getting new MOBO as well something from the top shelve.

 

Anyways thanks for any info on what I might expect and is it even worth it?

Andy,

 

I just went from an i7-2700K at 4.8 GHz to an i7-4790K two weeks ago, and absolutely love the results!  My new motherboard is an ASRock Z97 Formula OC, and I put in 8 GB of 3000 MHz RAM.  I'm currently running the CPU at 4.6 GHz and still have more headroom for overclocking as my peak temps during use of P3D 2.3 are in the high 50's to low 60's C using a Noctua NH-D14 heat sink/fans.  I have disabled Hyper Threading and Intel Speed Step.  I have also upgraded my graphics card to an EVGA GTX-780ti superclocked.

 

In P3D 2.3, I'm currently running default scenery and traffic with most settings maxed, except airline traffic at 50%, freeway traffic at 20%, no boat, ship or airport ground traffic.  I have HDR on, all shadows on except vegetation, and water at high with all water reflections on.  With custom fair weather (4/8 broken at 5000 ft, high cirrus layer, visibility at 30 nm), With the internal frame rate lock set at unlimited, I'm seeing frames around 45 to 60 frames per second and smooth flight.

 

I have not made any tweaks to the Prepar3d.cfg, except for disabling dynamic head movement.

 

This was not a cheap upgrade, but I'm very happy with the results.

 

Good luck with your upgrade!

 

Gerald

Thanks Gerald,

 

yes indeed not a cheap upgrade, basically a new computer as we can't simply stick the new cpu on the old mobo lol

 

so from what i am reading you are happy and I should see an improvement.

 

well i start price shopping I guess

The difference between an oc [email protected] vs an [email protected] isn't really that much. Perhaps 10-15% gain in framerate overall.

What does is most for you is the upgrade of your graphics card.

 

Having a [email protected] myself I will be waiting a couple more months for the Haswell-E octocore series.

My PC specs:

 

CPU: Intel i7 4790k @4.6Ghz 

Graphics Card: EVGA GTX 760 4GB OC 

Motherboard: Asus MAXIMUS VI Hero 

Ram: KingMax 16GB 1333mhz 

PSU: EVGA SuperNOVA 850W G2 

Case: Corsair VENGEANCE C70 

Cooler: Corsair Hydro Series H110

 

I'm not using FSX or P3D, I'm an X-Plane guy, so from my experience with my previous build, [email protected], I've gain the possibility to play X-Plane 10 with HDR on, (big FPS hog) and almost all other settings to high. I'm using 1/2 refresh rate from nVidia Inspector and never saw FPS bellow 30. 

I'm very happy with my setup, I will probably change the ram in the near future.

yup i was playing around checking out what drags me and in normal 1920x1080 p3d almost never drops  below 25fps no matter what i throw at it then once i stretch to my 3 screens 5760x1080 that's when i drop below 20's even as low as 10-12 (mind you that is with a lot of sliders to the max and me inventing stuff to throw at it like clouds rain etc...) normal flying is fine even with the surround on three screens, but i would hate to land in bad weather with a slide show of 12fps

 so yes i am now leaning towards the 780i instead of cpu and also waiting to see what the new haswell-e brings see if the 6in1 CPU's actually outperform i2700k in significant way for it to be worth $2k new rig.
