Verdict
The Radeon RX 7900 XTX and RTX 3070 land at effectively the same price so your decision should come down to features, ecosystem fit, and availability rather than budget.
The Radeon RX 7900 XTX's 24 GB of VRAM is a 16 GB advantage over the RTX 3070. At 4K or in heavily modded games that extra buffer matters — and it provides headroom as future titles push VRAM requirements higher.
As an NVIDIA card, the RTX 3070 gives you access to DLSS 4 super-resolution and Frame Generation, which can meaningfully lift frame rates in supported titles. The Radeon RX 7900 XTX counters with FSR 4, which is open-source and works across a wider range of games — including some that don't support DLSS. Which ecosystem matters more depends on the games in your library.
