Upgrade - GPU or CPU w/MB and more ram?

[Marius_S 4]

My current system:

MSI B85M-E45
Intel i7-4970k @ 4.4 Ghz
GTX 770 2 GB
8 GB RAM

At the moment it appears like I only will be able to either upgrade the GPU or the CPU with a new MB and more RAM.
My GPU is definitely ready for an upgrade, and I´ve been looking at the GTX 1070. However, I recently came across a good deal for a CPU upgrade which includes the following components:

ASUS ROG Strix Z270H Gaming, Socket-1151
Intel i7-7700k
Corsair Vengeance LPX DDR4 3000MHz 16GB

So, in your opinion, what would be my best choice here? I´m mainly using Prepar3D v3

As CPU-limited as flight sim is (in particular FSX), a 4790k is still a pretty powerful CPU.  It's very likely you're running into CPU limitations with a GTX 770 at times.  Certainly not all the time, mind you, but with complex add-ons and especially weather I can virtually guarantee you would benefit more from the GPU upgrade.  I just went from a 4790k to a 7700k and while there's a difference in performance in FSX, I'm running a 1070 so I'm not GPU-limited nearly as often as you are.

I would say that a 4970K @ 4.4 + GTX770 is a nicely balanced system.

Wait until you are ready to replace the whole system - sometime in the future.

Thanks for the advice guys. I found a good deal on a MSI GeForce GTX 1070 Armor OC, and ended up ordering that.

Let us know how it works out!

[Marius_S 4]

I will.

I´ve now done a few flights with my new GPU. The overall performance is about the same, but I do notice a big difference when flying into more "heavy" airports and weather. I don´t pay too much attention to FPS, but I´ve yet to get any stutters or low fps. 

So, as it stands now, I will postpone any furter upgrades until P3D v4 is released, and I know what will be required. I do hope my GPU will be ok for while now though.

If the overall performance is the same you haven't turned off Bufferpools in your config file.

That sounds about right.. enjoy the flying experience!
