Looking to build an AMD 9800X3D (or 9850X3D) + RTX 5080 desktop to replace my older 2019 gaming rig, and I would like some suggestions/pointers. Purely gaming.

Howdy,

Currently have an Intel i7 9700k + RTX 3070ti build that I've been using since around 2019, and looking to build a new system before prices get even more ridiculous.

I have access to Microcenter as well.

To start, I am thinking about the AMD 9800X3D or 9850X3D. I almost considered the 9950X3D until my preliminary research showed that the 9950 is really only good if I plan on doing productive or Blender types of work, which I don't.

For the GPU, I plan on getting a RTX 5080, but open to suggestions.

However, "what to buy" for the rest remains a bit of a mystery in the year of our lord 2026:

  1. B850 vs. X870E? The age old question. Even though I do not plan on using USB4 with this setup, I do wonder if the X870E will future proof me a bit?
  2. Motherboard: Microcenter does have some decent bundles such as this one, but I've read that the Strix boards have the ability to kill 9800-series AMD processors. I dont know how much of that is true vs. user error. My current Intel build uses a Gigabyte Aurous board and it's been extremely solid
  3. PSU: Do I need 1200W for this, or would less wattage actually be OK? What are some decent brands? Hope to have something that already has cables and has connectors that can directly work with the 5080. Currently have an EVGA SuperNOVA in this intel build and it's been pretty solid.
  4. Case: I am guessing Ill need a full sized ATX case. Right now I have a mid-sized Fractal Design Define C that has sound dampening and I love that aspect. Not looking for something flashy -- I dont need clear windows, RGB, etc.
  5. Memory: If I don't plan on getting a bundle with Microcenter, Ill have to scope it out a little bit. Open to suggestions here, also knowing that Microcenter typically does price matching.
  6. Cooling: Do I really need AIO with this, or would a higher end air cooler work just fine? I just want to be sure I am not causing too many heat issues with the 5080 in there as well.

I am sure Ill think of more questions after I post this, and if I do Ill edit this.

Any help greatly appreciated.
