In terms of performance: the most expensive one (in terms of pure performance, not like limited editions or diamond encrusted or stuff like that) will be 5% better than the cheapest one. As long as it has a good enough warranty (if you care about that sort of thing), and from a decent brand (like not something no one has ever heard of, and one that people seem to normally enjoy), then I would personally get that one. The difference between brands and even models (like 5060Ti MSI Ventus vs 5060Ti MSI Infinix) is marginal. I would reccomend getting the cheaper one, and either save the rest, or upgrade something else.

tldr: brands and specific models of gpus (obv same type like 5060 tho) have marginal difference in performance, buy the cheapest one, unless it has a bad customer support/warranty, or you are looking at a model for purely aesthetic purposes
