From about 2001-2004, I ran a typical computer fixit business, repairing, cleaning systems and subcontracting out to various local network and software consultants when they needed a "Windows OS /PC guy" to go on site. At some of the larger businesses (and even a few small, very well-run ones) there were some attempt at standardization, and tended to get either higher-end consumer or business-grade systems. But I usually ended up working on systems that were either from a brand name (from big box retailer like BestBuy; ordered from web site like Dell, HP, Compaq, Gateway, IBM etc.) or they had been sold by one of the handful of local computer stores.
The latter were, by far, the worst. I saw far more motherboards in those from companies like Biostar, DFI, Elitegroup, Foxconn, Freetech, Lucky Star, Matsonic, PC Chips, etc., than I did from companies like Abit, EPoX, IWill, Shuttle, Soyo (which I considered to be good mid-tier brands, not too expensive) or even top-tier manufacturers like ASUS, Gigabyte, Intel, MSI, SuperMicro, Tyan, etc. I spent a lot of time doing things like hunting down motherboard manuals, BIOS updates, vendor-specific drivers (when silicon drivers from ALI, AMD, Intel, SiS, ULI, VIA, Winbond, etc. would not enumerate) and the like. Aside from crashing (which, admittedly, could often be due to Windows 95/98/Me/2000/XP cruft) these computers were never great performers even with a fresh OS load, reinstall of apps, patching and restore of old customer data. Another thing they all had in common was that the computer owner had usually been told they were getting a "super high-end" gaming computer, workstation, etc., and instead had been given systems with low end Celerons (for Intel) and a lot of Durons and Semprons (for AMD). I remember one person, a moviemaker, who paid thousands of dollars for a nonlinear digital editing workstation, and got a Pentium 4 CPU on a motherboard that used PC133 SDRAM. Not exactly the kind of high-performance component to put into a system, especially when RDRAM and DDR-RAM were battling it out for "who's fastest" on the desktop.
I think you've had some strange AMD motherboards go trough you if you have had problems with issues, components or missing drivers. Of course I've only dealt with higher end mobos like Sabertooth or Asus PRO versions but those two haven't had a single problem. Just put the CPU in and you're ready to go, except of course for graphics drivers since AMD CPU's don't have an IGP.
Sure there have been some pretty crap mobos, especially from the early GB versions but thats on them I think not AMD. I had and 970 something mobo from GB and that plain out sucked, after that I just went with Saber and got to say, it's one of the best AMD mobos out there. I don't even thinkk after Saber the ROG version is worth it's price.
