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 7700 XT

Clearance 1440p value

Superseded but strong value — at clearance pricing, a capable 1440p card for well under $350.

12GB GDDR6

Comfortable VRAM for 1440p gaming.

Mature RDNA 3 drivers

Well-optimized after 18+ months of updates.
