Why buy each?

NVIDIA RTX 4090

24GB GDDR6X — more VRAM than RTX 5080

More VRAM than the RTX 5080 (16GB), relevant for AI workloads and 4K texture packs even in the Blackwell era.

Used market only

New retail units are scarce and priced above MSRP. The used market (eBay, local classifieds) is the only viable path to value.

Mature driver ecosystem

Over 3 years of driver optimizations make this one of the most stable GPUs available.

NVIDIA RTX 4080 Super

Used market value

New units sell above MSRP, but used units (~$800) represent the only realistic value option for this card.

16GB GDDR6X

Ample VRAM for 4K gaming and content creation.

Mature Ada Lovelace drivers

Over 2 years of optimizations ensures stability across all titles.
