Any reviews I've seen show a 2-10% performance drop over other boards (even other AsRocks) due to the older technology. Great if you really need the functionality, but I'd avoid if you can upgrade memory/GPU as well. Not quite the gem the 939 DUAL-SATA was.
"Our results confirm that there is not a throughput performance penalty for using AGP over PCI Express on the ASRock 775Dual-VSTA. In fact, just the opposite is true in this case as our AGP graphics cards consistently scored better than their PCI-E counterparts. This is attributable to the PCI Express Graphics slot being limited to X4 operation at the upper resolutions and the slight overhead penalty incurred due to the VIA chipset design. However, the performance of the PCI Express slot is not that bad with the worst penalty being around 5% with our video cards. (Pairing the motherboard with a top end GPU results in performance that can be up to 10% slower in certain applications than competing motherboards.) If you have either an AGP or midrange PCI Express card then this board will handle both in a more than acceptable manner with today's applications."
a good value motherboard. the downside of its cpu performance vary from 1% to 10% compared to other premium boards. its pci-e only run in only 4x mode due to chipset limitation, but the agp works great at 8x mode. it only has two sata interface. not so overclockable (up to fsb 297 mhz), i noticed that via chipset has this 5-12% overclocking ability.
sometimes it freezed my samsung syncmaster 793mb crt monitor when doing both cold and warm boot, needed to plug off the power cable off from the monitor and replugged in again to make it worked while the system was stable enough using the default bios setting. i didn't know what's the problem of mine, perhaps it was the board, vga agp, or the monitor. but when i tested it on other crt and lcd monitor it worked fine. and when i tested my monitor to other system, it worked fine too! *strange but real. don't know what is wrong..
its temperature range in 30 to 43 celcius degree while the smallest degree was at idle and 43 degree at full load.
just remember to update to the lates bios to make it works at decent performance.
overall satisfying is what you will get if you're not into any overclocking thing.
here is mine:
