I don't need the iGPU, my dGPU is a 3080TI.

I’ve been an intel boy since I first started building computers in 2014.

Buy an AMD.

Amd

Either is fine but i strongly recommend going for amd, especially an x3d one, like 7800x3d(if you care about gaming).

I was wondering if there would be any conflict in having an AMD CPU and an Nvidia GPU.

No.

The GPU doesn't care about the CPU, or vice-versa. AMD is probably better value for money right now if you're intending to replace both CPU and mobo, but Intel will work.

The reason you don't see AMD CPU + nVidia GPU in premade machines these days has to do with corporate contracts, not interoperability. Before AMD bought out ATI, it wasn't an uncommon combination.

Nah, anything will work fine.

Just a quick question, are you sure it’s the cpu that died? Those ivy bridge (?) chips really seem to last. I’d be surprised if it was the cpu and not the motherboard or power supply of something.

You have one of the nicer fourth gen chips. It would probably be worth it to take it to a computer shop or something and have them try to boot it with a good board.

If it’s still kicking, those motherboards are cheap as heck. The ddr3 is cheap too.

No reason not to keep it around to run a file server/seedbox/Jellyfin server/whatever.

Go AMD.

There is basically 1 reason to go Intel cpu: quicksync video encoding. Amd's is fine but intel's is the gold standard.

Otherwise definitely go amd, it rocks Nvidia perfectly.

CPU is pretty much irrelevant to GPU choice.

Personally I wouldn’t buy any recent intel CPU with the dishonesty and major flaws in their products as of late, but that’s up to you to decide - AMD’s most recent CPUs haven’t been amazing either, but don’t have hardware flaws at least.

As others said, both work just fine with any GPU and Intel had serious issues lately with crashes. I'd say go with AMD unless you want higher power usage as Intel chips fare worse when it comes to perf/watt metrics. That said Intel CPUs might have an advantage at single threaded loads, but again, at much higher power use. AMD also tends to keep CPU sockets for longer thus less motherboard changes are required if you upgrade the CPU. You might also consider reading reviews on serious technical websites as it might give you inside into what performance and prices to expect.

Update: On more (implicitly expressed consequence) - due to Intel's much higher power requirements, they are more difficult to cool down - more expensive (air) coolers and quite possibly water cooling required.

Any Linux distribution should work on AMD CPUs, well, Debian based distros can sometimes have issues with particularly new hardware due to the long time between releases. But bazzite is fedora based so you should be fine with anything.

Nvidia GPUs work just fine with AMD CPUs.

Realistically the question is how high end of a CPU do you want, the mid to high end range AMD CPUs tend to be cheaper than their intel equivalents, but the highest end intel chips edge out the highest end AMD chips right now. Realistically, that won’t matter unless you are doing something super CPU intensive and just want the most power possible for your machine.

AMD CPUs also have better integrated graphics, not super important if you have a dedicated GPU, but, there are times when having a second somewhat capable graphics processor could be useful.

On Linux, AMD GPUs work significantly better than Nvidia ones. If you have a choice, choose an AMD. Nvidia is mostly fine though. Even Wayland works well on Nvidia now (after the 560 driver release).

Sometimes you'll hit issues with memory management if you have <=8GB VRAM, since the Nvidia driver doesn't support swapping infrequently accessed parts of VRAM into regular system RAM, like it does on Windows and like AMD does on both Windows and Linux. It's a long-standing issue.

You may also need to manually reinstall the driver after kernel updates. In theory, it's improving as Nvidia are moving most of the driver logic into the firmware, and making the driver thinner with the new open-source out-of-tree driver (https://github.com/NVIDIA/open-gpu-kernel-modules).

For CPU, I'd definitely go with AMD instead of Intel. Intel aren't having such a good time at the moment.

AMD
