Quick Answer

Yes. The RTX 5090 runs Pillars of Eternity 2 without breaking a sweat at 1440p (QHD), holding well into triple-digit frame rates at native 1440p. In a South African build the RTX 5090 sits around R45,000 to R55,000 when stocked at Evetech, and Pillars of Eternity 2 is an isometric RPG that is light on the GPU and friendly to laptops.

What to actually spend on

Because the RTX 5090 clears Pillars of Eternity 2 so comfortably, the smart money goes into the parts you notice every day. At 1440p (QHD) you want a monitor that can show the frames the card produces, a CPU that does not bottleneck fast scenes, and enough storage for large installs. The RTX 5090 is overkill for Pillars of Eternity 2 alone, so treat it as a card that future-proofs you for heavier titles. Stocked near R45,000 to R55,000 at Evetech, it is a long-term buy rather than a single-game purchase.

Pairing it with the rest of your SA build

A RTX 5090 only shines when the rest of the rig keeps up. For Pillars of Eternity 2 at 1440p (QHD), pair the card with at least a current 6-core CPU and 16GB of RAM so the GPU is never starved, and budget for a 650W or larger 80 Plus PSU with good case airflow. The RTX 5090 draws meaningful power, and in warm South African rooms cooling is what protects sustained clocks. Evetech lists the RTX 5090 around R45,000 to R55,000, so plan the supporting parts into the same budget rather than maxing out on the card alone.

FAQ

Do I need DLSS to run Pillars of Eternity 2 on the RTX 5090?

No. The RTX 5090 holds well into triple-digit frame rates at native 1440p at native 1440p. DLSS 4 is there as a bonus for even higher refresh targets, not a crutch.

Is the RTX 5090 overkill for Pillars of Eternity 2?

For this title alone, yes. Pillars of Eternity 2 is an isometric RPG that is light on the GPU and friendly to laptops, so the RTX 5090 leaves huge headroom. The card earns its R45,000 to R55,000 price on far heavier games.

What CPU should I pair with the RTX 5090 for Pillars of Eternity 2?

A current 6-core chip or better keeps the RTX 5090 fed in Pillars of Eternity 2. Since an isometric RPG that is light on the GPU and friendly to laptops, a faster CPU helps frame consistency more than minor GPU upgrades would.

TIP

SA Setup Tip

Enable upscaling in Quality mode first; it usually buys 20 to 40 percent more frames with little visible loss at this resolution. The RTX 5090 is currently stocked at Evetech around R45,000 to R55,000.
