I just upgraded my GPU to a 4070 Ti S. Seems my 11400 might need to be replaced to make better use of the GPU.
How high do I need to start looking for in an 11 series?
Main use is driving three screens (1080/1440/1080) in Microsoft Flight Sim.
Which Intel 11 Gen CPU for My 4070 TI Super

I don't expect to find anything new so will be looking for used and I bought an extra 16Gb on Monday to take me up to 32.
Just missed out on an 11700KF by a day :(
There are some online calculators that you could use to check this.
I just did and says your 11400 will have 40% bottleneck at 1440p (assume single, not triple monitor).
What GPU are you currently running? When one of my games was running sluggish, I too thought about upgrading my GPU but actually found that it was the CPU that was the bottleneck. I upgraded the CPU and everything else required for it, then the current GPU was able to run the game smoothly.
Up until the weekend I was using a 3060 Ti. Unfortunately I didn't know about the built-in FPS developer tool in MSFS prior to the upgrade so have no in-game prior baseline to compare against.
let's just say i7 11700k == i9 11900k
Unlike other generation, for 11th gen specifically, the core count or the cache capacity on i7 and i9 is IDENTICAL, there are minor frequency difference but it doesn't affect performance almost at all.
also 11th gen introduced Memory Controller Gears which significantly limits the memory frequency capability, to 3600 (3733 if lucky). down from 4266+ on 10th Gen. The raw latency of mem controller also significantly increased…
compare to 10th gen, 11th gen uses the same 4 wide instruction decoder, and maximum of 16MB L3 instead of 20MB on i9 10th gen…. making the gaming performance sometime worse than 10th gen even though the CPU itself is faster..
If you really want to do an upgrade, should consider 10900k >= 10850k > 11700k > 11900k
but the thing is…. 12600k matches 10900k in gaming performance and workload performance (when e-core scheduling works), do you really want to waste money buying 10/11th gen??
Thanks for that great info. Anything other than 10/11 means a new MB and after buying an extra NVME drive, RAM and GPU this week I'm pretty much stuck with 10/11 gen. I believe I lose my primary NVME socket too with a 10 gen CPU on my B560 Aorus Pro - (M.2 connector * Supported by 11th Generation processors only)
just swap mobo and CPU (maybe cooler), re-use everything else.
You have DDR4 RAM, new mobo will take your old NVMe anyway (Win10 /11 is quite good with migrate to another PC without getting instable).
sell your CPU and mobo for couple hundreds, and add some $$ to get 12600k/13600k, with a B760, you'll be all set on the bleeding edge again.
Ended up swapping to a 11700KF for $200. Appreciate the input though, was very useful, but was limited with $$$ for now. The upgraded GPU, RAM and CPU will see me out for a while I think.
Do you want to stick to a budget? Go the i9. Otherwise probably the i7.
You might find it hard to source an 11th Gen though, seems like Amazon is about the only place that has them and there are slim pickings.
I run 3 x 4K monitors on an 12th Gen i9-12900K (was a 13th Gen, but had issues) with a RTX 2060 D6 12GB GPU no problem. Run Adobe Suite and other stuff very well. Not a gamer, just work computer.
Whats your overall RAM as well? You might need to consider upgrading that as well.
