ASRock 939Dual-SATA2
Speaking positively we can mention that 939Dual-SATA2 is rather well-rigged product. You at least will get one SATA-II port, good power stabilizers and acceptable mixture of old and new interfaces (serial and parallel ports together with USB 2.0). Furthermore, overclocking options are quite competitive if compared with more expensive products. Finally we should note the upgradeability to upcoming AMD Socket M2 (to be released in mid 2006) by installing an additional card. At the same time it would be good to see BIOS update which could solve the performance lag. In that case the 939Dual-SATA2 may become a very popular solution.
