I upgraded to an RTX3060TI FE from a GTX1080 FE and it was noticeable. But my main concern is the lack of VRAM on it. The RTX3060TI does have much better Raytracing(RT) performance,but I am not sure how long RT will be playable on the card - even in Cyberpunk 2077 I needed upscaling to enable some RT effects.
A few months the RX6700 non-XT was around £300ish,but the RX6700XT AIB models are cheaper than the RTX3060TI AIB models.
IMHO,only the RTX3060TI FE for around £370ish makes sense in terms of price/performance. If going for AIB cards,the RX6700 series is generally better value especially if you don't really care about RT in games.
