I think £600 will only fly if it’s at least 20% faster than a 4070 as traditionally £500 got you a card equivalent to the previous gen top tier model of which the 4070 has a defect of over 25% to the 3090ti.Just saying the 7900XT is now available & in-stock for £750 on OCUK. Who knows what the 7800XT will actually be, but it certainly won't be £750. I think your £600 is closer to the mark based on the price & performance of the 7900XT vs 7900XTX.
