Summary: What can I say, look at that price. For $70 you get a full-fledged board which will facilitate the transition from AGP to PCI-Express with its two slots. You can use your "old" AGP card until you actually see any benefit from going PCI-Express, or have the money.
Unlike other manufacturers' solution neither the AGP or PCI-E x16 port suffer from performance penalties. Both are native implementations. ULi has done a great job with this chipset.
Pros: Awesome price, AGP 8x and PCI-Express x16, Good performance, Good overclocker, but only after modding, Extra SATA-II port, Can be upgraded to Socket M2, Silent
Cons: BIOS offers very little OC options, Needs modded BIOS and voltmods for serious overclocking, Only 100 MBit networking port, Slim accessories, No Firewire
Excerpt: Recently we took a look at one of the newest players to the chipset market, ULi. While having a new name, ULi is actually the acquisition of ALi by the ULi group. ULi has started to show its cards over the last 3 months, bringing out its first all out attempt at the AMD Athlon 64 market with the M1695, a very innovative chipset when added with the latest in ULi's Southbridge's.
Conclusion: The ASRock 939Dual-SATA2 comes at a very opportune moment in the PC market where we are on the verge of another major shift towards a new socket platform for AMD processors. Do you have a relatively high-end AGP graphics card (like a GeForce 6800 ultra) and are unwilling to make it obsolete just to move on to the newer Athlon 64 processors?
Excerpt: Desde aquélla primera review que apareciera en nuestras páginas sobre la Asrock K7S8X-E mucho tiempo ha pasado. Esta vez, la marca subsidiaria de ASUSTek vuelve a pasar por nuestras manos mediante una placa base que está dando mucho que hablar entre otras cuestiones por su excelente relación calidad/precio, cuestión que ya no nos sorprende en este fabricante.
Excerpt: Esta marca acaba de lançar esta motherboard que suporta os dois slot's para placas graficas, ou seja, AGP e PCI-E. O que é muito bom para quem tem uma placa AGP e futuramente queira mudar para uma placa gráfica.
Tem o chip7 ULi 1695, que é equivalente a um nForce4.
Uma boa escolha para quem tem AGP.
