Quick Answer
Yes, the Arc B580 (12GB, around R7,000 to R8,500 at Evetech) can drive GTA 6 at 2560x1440 and 240fps, but 240fps at 2560x1440 needs XeSS 2 plus competitive-style low settings in GTA 6 to keep frame pacing flat. Pair it with Ryzen 5 7600 or Core i5-13400F (Resizable BAR on) and a 240Hz panel (Samsung Odyssey or comparable) to actually see 240fps. Set an in-game cap near 243 and enable XeSS 2 before you touch image quality.
The 240fps Target at 1440p Explained
A clean 240fps run at 2560x1440 is well within reach once the display chain and a few key sliders are sorted. First confirm your monitor is actually running its rated refresh in the AMD, NVIDIA or Intel control panel, then set the game to exclusive fullscreen at 2560x1440. With 12GB of VRAM the Arc B580 sits in the budget bracket, so 240fps at 2560x1440 needs XeSS 2 plus competitive-style low settings in GTA 6 to keep frame pacing flat. Apply XeSS 2 early, set a frame cap a few frames above 240 to keep input latency low, and only then start lowering quality if the 240 line still dips during a rainy night drive through downtown Vice City with traffic, neon reflections and crowds.
In-Game Settings for 1440p 240fps
GTA 6 is one of the most demanding open-world titles on the market, with dense Vice City crowds, wet-weather reflections and long draw distances that hammer both GPU and VRAM. The biggest frame-rate wins come from reflection quality and population density; take both to medium first and retest in a rainy night drive through downtown Vice City with traffic, neon reflections and crowds. Next trim shadow distance and volumetric lighting a single step, keep texture quality on high for image quality, and leave textures as high as your 12GB buffer allows without stutter. Retest the same scene after each change so you can tell which slider bought you the frames, then lock the cap near 243 once the 240 line holds.
FAQ
How much does the Arc B580 cost in South Africa?
Expect roughly R7,000 to R8,500 for the Arc B580 at Evetech, depending on the board partner and current stock. That puts it in the budget class with 12GB of VRAM. Prices shift with the rand, so check the live listing before you commit.
Do I need XeSS 2 to hit 240fps in GTA 6?
For 2560x1440 at 240fps, yes, XeSS 2 makes the target far more comfortable on the Arc B580. Run it on Quality first; only step down to Balanced if a rainy night drive through downtown Vice City with traffic, neon reflections and crowds still dips below 240. It costs almost no image quality at this resolution.
What CPU should I pair with the Arc B580?
A Ryzen 5 7600 or Core i5-13400F (Resizable BAR on) keeps the Arc B580 fed at 2560x1440 without bottlenecking your 240fps target. At higher resolutions the GPU does most of the work, so a mid-range CPU is plenty; spend the saved budget on faster RAM or an SSD instead.
Evetech Tip
Set your XeSS 2 mode and a 243 frame cap before lowering any visual slider in GTA 6. If frames still dip in a rainy night drive through downtown Vice City with traffic, neon reflections and crowds, a Arc B580 (R7,000 to R8,500) is the cleaner fix than micro-tuning a weaker card.
