FUD Zilla reports it will take a while until you see better availability of ATI's Radeon HD 4770 because the yields of these 40nm cards aren't that good yet. A second batch of RV740 GPUs is expected in the first week of May, and it will likely take until at least June before there will be enough supply of these cards.
The first batch was delivered before the launch and the second batch is expected in first week of May, or should we simply say next week.
Even the next batch won’t satisfy the needs of customers and we believe it will take at least a month if not even more before ATI can pump enough 40nm RV740's into the channel. This was the case with the RV770 launch last year, as this 55nm card was a great performer, but very hard to get in the first month following the launch.
