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 5080

Sweet spot for 4K gaming

Delivers excellent 4K frame rates at a lower TDP and price than the 5090 — the practical enthusiast choice.

DLSS 4 Multi Frame Generation

Same DLSS 4 technology as the flagship, dramatically boosting frame rates in supported titles.

360W TDP — practical power draw

Runs on a 750W PSU comfortably, unlike the 5090's 1000W recommendation.
