Is this PC good for 4K gaming?

Yes. The RTX 5090 is the fastest consumer graphics card, so it handles 4K at high settings and high refresh rates, including ray-traced games. Pair it with a 4K 144Hz or faster monitor to use it fully.

Can I upgrade the RAM and storage later?

Yes. It uses standard DDR5 memory and an SSD, so both can be expanded. Check the motherboard's free slots and M.2 bays before buying parts.

Does it come with Windows installed?

Yes, Windows 11 Home is preinstalled. You set up your account on first boot.

Is the Core Ultra 9 285K good for video editing?

Yes. Its many cores and high clock speed suit editing, rendering and streaming. 32 GB of RAM is fine for most 4K editing; very heavy projects may want more.

What monitor should I pair with it?

A 4K display at 144Hz or higher, or a 1440p high-refresh panel for competitive games. The card can drive either comfortably.

How much power does it draw?

A build with an RTX 5090 and a 285K draws a lot under load, so it needs a strong power supply and good case airflow. Check the included PSU wattage before adding more drives.
