Upgrading CPU and Mobo

[celerystruct]

Budget (including currency): ~$500 (US) (Flexible on this)

Country: USA

Games, programs or workloads that it will be used for: Gimp, DaVinci Resolve, Dragon's Dogma 2, Cyberpunk 2077.

Other details (existing parts lists, whether any peripherals are needed, what you're upgrading from, when you're going to buy, what resolution and refresh rate you want to play at, etc): 

 

My 5900x is dead so I am taking the opportunity to upgrade the mobo as well.

I would like to reduce the size it take up as well so I'd like something that is mATX or smaller. I'm considering the Lian Li A3 case, I'm open to other similar suggestions as well.

I'd like recommendations on a good CPU and mobo. If possible please list alternative options for the mobo as I'll be looking at the clearance section of my local microcenter to see if I can get the price down.

I also have 4 ssd drives so if there's any concerns about the case please let me know.

Also I'd like to know if the PSU I currently have is sufficient for that set up. I'm not sure why my CPU died but someone told me it might be due to my PSU supplying insufficient power to it.

Thank you!

And how was it verified it was dead?

 

Because a cpu is normally the least likelt component to die.

 

Either way for 500 you are not getting a cpu, ram and board thatll be better than what you had mostly because ram prices are stupid rn. 

 

A ryzen 7700 budget b650 and ehatever 32gb kit of fastest ddr5 you can afford (plus like a thermalright cooler) would be a goto bundle upgrade

 

The ssds are they all 4 nvme or sata/nvme mix?

 

What board did you have?

Yes, I understand that cpu is the least likely to fail. It was verified dead when after replacing every component one by one than all at once except for the cpu (Because I don't have a spare one) it wouldn't boot up still. I had a spare of every part except for the cpu. I took it to microcenter for diagnostics for good measure and they also confirmed all my parts are fine and that it is the cpu since after they swapped the cpu out my pc was able to boot.

 

Also I never asked for RAM. I know ram prices are stupid right now so I'll be sticking to the sticks I already have. The ssds are one nvme for my os and 4 sata for storage.

 

My previous board was a gigabyte x470.

 

I haven't kept up with cpu benchmarks in forever so I was just looking to get some recommendations from people for something that'd be comparable with the new stuff

Then you have to buy older stuff. As well everything new is ddr5 only.

 

If all parts are ok cept cpu id just get another 5900x if thats what you need and call it good. They are quite cheap now
