TUL adds an upgrade to the HD4770 series, the custom cooled PCS HD4770. The card clocks in with a 750MHz core speed and 800MHz of memory speed cooled by ARTIC COOLING. The PowerColor PCS HD4770 will retail for US$109 and will be available on August, 10th.

The situation right now seems a little unfavorable for AMD as the Radeon HD 4770 stocks ran dry the moment the cards hit the market. Switching over to Radeon HD 4850 and HD 4830 might help a little but it seems HD 4830 stocks are running dry too.
