7900XT, XTX or 9070XT

Currently going through a full rebuild, only thing I'm stuck on is the GPU. Do I: A. Buy a 7900XT for around £600-650. B. Wait to see if the price of a 7900XTX comes to down to anywhere between £790-850 Or C. Wait for the 9070XT release and either re-evaluate the cost of options A and B or Buy the 9070XT pending benchmarks?

Can list the specs of the PC build if the community wishes to provide further context.
