Some just prefer sticking to something that they are familiar and that they have used.Some gpu’s like Gigabyte come with a 3 month warranty and others with 2 years. Buying used is a gamble you don’t no if it’s been refurbished atleast new comes from an authorised dealer
Good brands for me are msi,evga and asus.
Also heard good things from zotac but haven't personally owned one.
That is so true, no room for being a bad brand. I guess the only thing is after sale supportThere really is no such thing as a bad brand these days sticking to the mainstream names.
