Verdict
The Radeon RX 7900 XTX and RX 6600 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 RX 6600. At 4K or in heavily modded games that extra buffer matters — and it provides headroom as future titles push VRAM requirements higher.
If we had to pick one: the Radeon RX 7900 XTX edges it on raw VRAM, which carries more weight the longer you hold onto a card.
