Rtx 5080 and RX 9070 xt

Good night! For a 4k oled 250hz monitor and R7 7800X3D, wich GPU do you buy?

Rx 9070 xt- 650€
Rtx 5080- 1200€

545€ of difference, whats your opinion?

I've seen criticisms of the MFG x4/x6 due to latency, but in many videos the latency only increases by about 7 ms. That's not so bad, is it?
