PCPartPicker is my go-to recommendation for validating a build before you buy anything. It takes the guesswork out of compatibility and lets you see community builds, which is super helpful when you’re targeting Blender performance.
You'll be taken to Pcpartpicker to complete your purchase.
“To make this easier, I recommend using tools like Build My PC, PC Part Picker, or MicroEnters PC Part Picker, which help you select compatible parts and show you community builds specifically for Blender, so you can see what others are using and how much it costs”
