Because thats how much this card costs in my country ATM. On sale it was $295 but the sale is over the price is back to 376. I know its way off MSRP but my only options are wait for another sale or wait for NAvi to maybe bring prices down
It is impossible to say if it's worth it without knowing what your country is and what the prices of other higher and lower performing cards are.
Additionally, knowing what your current GPU is, and what your use case is, would be very helpful.
