Buying call

Buy an RX 7900 XT card at a discount if you want 4K-capable gaming with 20GB of memory: reviewers praised its 4K performance and cool running, and it beat every last-generation card. Skip it near launch price, because reviewers said the faster RX 7900 XTX was the better buy for a little more. Nvidia also has stronger ray tracing and software.
