Is It Worth Upgrading from RX 6600 XT to RX 7800 XT on a Tight Budget?

Hey everyone! I'm contemplating a GPU upgrade from my current Sapphire Nitro+ RX 6600 XT to an XFX Speedster SWFT210 RX 7800 XT. My budget is really tight, but I have a trade-in offer for my 6600 XT at $155, which brings the 7800 XT's price down to $258. I mostly play story-driven games at 1440p and want to maintain high settings with a smooth 60+ FPS. With future games using Unreal Engine 5 potentially lacking optimization, how future-proof do you all think the 7800 XT is over the next 2–3 years? Also, even though the 7800 XT doesn't support FSR 4.0, it does support FSR 3.1. Will that be enough to enhance performance? Lastly, any thoughts on the XFX Speedster SWFT210 model in terms of cooling, noise, and overall performance? Here are my system specs: CPU: Intel Core i7-12700F, Motherboard: ASUS ROG STRIX B660-A GAMING WIFI, RAM: 32GB DDR5-5200 MHz, PSU: Corsair 750W, Case: be quiet! Pure Base 500, Monitor: 1440p 170Hz. Thanks for the help!
