if the price difference is huge enough (like, you get 2 gpus buying overseas after paying taxes etc, but only get 1 gpu for the same amount of money on your country), i think it's worth to try. if not, probably not. for example, in my country the gpus supply suck so bad, but buying overseas doesn't help that much even if there's a difference of $200-300 since we need to pay taxes etc.
I think this tax thing is for those in the U.S and other part of the country, this doesn't apply to me since I'm in Africa I don't pay tax when buying items from outside country, the only issues I get is waiting for a long time to get the goods and logistics prices are sometimes higher too
