Chinese New Year blamed for delay of Radeon HD 5830
 

We were told that these GPUs are going to be delayed to factories and that it won’t make it to China before February 10. At this time most factories are closed for the Chinese New Year and won't open their doors for anyone. This might delay the shipping until February 20th.

Without further words you can expect that Radeon HD 5830 will ship after this date and volume availability can probably be expected in March.
