Why is this R9 280x cheaper than the others?



Is it true that the above GPU is just on sale? It's still pretty much the same as the other 280x's right?
 
ya--i will admit my last sapphire card was not so good and i replaced it with in 5 months ,but just could of been my turn to get a lemon . it haf shuddering and would not display any crt monitor . fooled with it for 4 months and decided to replace it, and the replacement card [not sapphire] work fine right out of the box no issues

after you spend $250 for somthing that dont work as expected its hard to go back to them twice in a row
