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.

AMD RX 9070 XT

16GB GDDR6 — VRAM advantage

4GB more than the RTX 5070 at the same price. Future-proofs for 1440p ultra and 4K textures.

FSR 4 with ML upscaling

AMD's first machine-learning upscaler, narrowing the gap with DLSS 4.

No vendor lock-in

AMD's open-source driver stack and FSR's open standard avoid proprietary ecosystem dependencies.
