Question How much bottleneck will I get with the 3700x and the 4090 GPU

I'm upgrading my power supply to a 1000W and currently have the Ryzen 7 3700x. I have a 2k monitor and will be playing in 2k as I do now but also 4K hence why I am getting the 4090.

The question is will I notice a lot of bottleneck in 2k?

an extra 8-20 fps loss in 2k if you got a more expensive CPU like a 5800x. If you grab a 7000 series CPU with DDR5 RAM that gap goes to like an extra 40-70fps depending on games at least. 4k will probably be less CPU limited and harder on your GPU so half those differences roughly??

A 3700x will make your 4090 perform like a 4080 on new gen hardware. 5800x3d or 5700x if you want to go the cheaper route and maybe upgrade to AM5 next round when they drop their next X3d chips.

I've got the same CPU mated with a 6900xt and am buying a 5700x to keep things smooth for a few years before swapping platforms to AM5

My math says I can sell the 3700x for $100 give or take 20% & buy a 5700x for $190... under $100 upgrade will keep me happy for a while. https://www.ebay.com/itm/125522220531

Initially I was thinking 5800x3d or 5800x but the upcharge for the x3d is a little high for my rather limited gaming & the 5800x is within 1% of the 5700x. Benefit of the 5700x over both 5800's is it runs considerably cooler than both.

That means I can keep on air cooling and still have 60C gaming & no loud and annoying AIO.

Realistically speaking the next few years should bring back cheaper PC parts (Waiting for AM5 boards, DDR5 to drop) & with AMD Pushing both Nvidia & Intel we should get some pretty impressive generational improvements & low prices to boot. Can't complain about that & a welcome change from the last few years.

Or could grab a 5800X3D for similar performance increase without needing a new motherboard or RAM.
 
You will have no bottleneck.
If, by that, you mean that upgrading a graphics card can
somehow lower your performance or FPS.
A better term might be limiting factor.
That is where adding more cpu or gpu becomes increasingly
less effective. 4090 is as good as it gets.
You may still find that at 4k resolution, the 4090 is the limiting factor.
Whatever, you WILL do better with the 4090.
 
Would my X570 ultra be compatible with the 5800X3D. Why is the 5950X £100 more than 5800X3D .
I would expect your motherboard would be compatible with a BIOS update. Need exact model to check but it should be. The 5950x has 16 cores and 32 threads but games cannot use that many (I can think of 1,exception), most games don't use more than 8-12 threads. The 5950x compromises single core performance which is more important for gaming. The 5800x3D with its 3D cache is a good margin better than the 5950x at gaming, the 5950x was never the best gaming choice being outperformed by the 5900x. However in multithreaded applications and heavy multi-tasking the 5950x is a much better cpu. For gaming with a AM4 motherboard the 5800x3D is the clear winner, but if you do more than gaming and can utilise the extra threads then a 5900x/5950x may be a better choice. Its about picking the right tool for the job.

The motherboard will be compatible with the latest BIOS. Assuming this is your board. But even the old B350 boards can now run all 5XXX processors with the latest bios, even if they are under equipped for the task.
