Is 8 GB of video memory enough for Fortnite?

Yes for the tiers this card can reach anyway - its core speed runs out before its 8 GB of video memory does in Fortnite.

Can I run Fortnite with a GeForce GTX 1080?

The GeForce GTX 1080 already carries the 8 GB that high asks of Fortnite. What it does not have is the core: that tier is a GeForce RTX 3060 Ti, and this card reads 11 against its 18.

Of the 8 cards that reach this same point in Fortnite, the GeForce GTX 1080 is the slowest - index 11 is the least this game will accept for that tier among the hardware we track.

The weakest link is graphics card: this rig brings 11 against the 18 that Fortnite asks for at the high tier. Everything else in the rig is already past that line.

That readout is the best this card can do in Fortnite: it assumes nothing else in the machine holds it back. Your own processor and memory can only lower it, never raise it.

The same card with three different processors

In Fortnite the processor beside a GeForce GTX 1080 changes the answer, which is why a card-only verdict is not worth much here. Each row assumes 16 GB of system memory.

Processor	Index	Verdict	Bottleneck
Ryzen 5 1600	30	Will not run	processor
Ryzen 9 5900X	70	Runs well	graphics card
Ryzen 7 9800X3D	95	Runs well	graphics card

Cheapest way up one tier

graphics card: Arc A750

The GeForce GTX 1080 sits at index 11 and the high tier starts at 18.

That is the smallest part in our catalogue that clears the high tier - not the fastest one, and not a price claim: we hold no price data, so "cheapest" here means "least upgrade that does the job".
