What you get

The RTX 5080 is a 4K-capable card with 16 GB of GDDR7 and DLSS 4. For GTA 6 we expect it to handle ultra settings, and with upscaling it should hold smooth frame rates at 4K.

What you do not

You do not get the large VRAM reserve of a 90-class card. 16 GB is enough for today's games but not generous. If your plan involves heavy modding or extremely high-resolution texture packs later, that is the number to think about.

Against the RTX 4090

The 4090 is generally faster in raw rendering and has 24 GB. The 5080 counters with newer features and lower power draw. For a first purchase, the right answer depends on price and availability; for an existing 4090 owner, there is no reason to switch.

An ultra profile to try

• 4K, ultra settings, DLSS Quality.
• Ray tracing on a medium setting if frame times stay even.
• Multi frame generation only for very high refresh rate displays.

Power supply and the 12V-2x6 standard

Recent ATX 3.0 and 3.1 power supplies come with a native 12V-2x6 cable, which is the cleanest way to power this card. If you use an adapter from older 8-pin connectors, make sure it is the one supplied or a quality replacement, and that the plug is pressed in fully until it stops.

Should you wait for something newer?

There is always a refresh around the corner. For GTA 6 specifically, the relevant fact is that no PC version has been announced, so waiting costs nothing. If you need a card now for other games, buy the one that suits them; if GTA 6 is your only reason, wait for real PC requirements.

What to look for in the PC port's first reviews

When reviews of an eventual PC version appear, three things tell you whether a 5080 is comfortable: video memory use at 4K with the highest textures, whether performance changes sharply when you move to a weaker CPU, and how long shader compilation stutter lasts at first launch. Those, more than any average frame rate, show how the card will feel in real play.
