Sorry about thatYou were supposed to just be looking at the power figures!
I've watched a few other comparison videos and the 7900XT really does seem the better card in regards to a few of the games I mentioned in my original post like Baldur's Gate 3 and Starfield, not sure which is better for World of Warcraft as no one really tests that one.
I have 4 weeks to be able to return the 4070Ti Super so I'll do some further research on VR and Flight Sims, though to be honest I rarely play Microsoft Flight Simulator much these days so I won't use that as a deciding factor, Warcraft is the main one.
I might even be able to stretch to one of the cheaper 7900XTX's i.e the ones under £900.
Thanks again.
