DELL!!! Jk. I was googling companies and the answers I was gettting were, quite honestly, stupid. So I'll start.
Asus is definitely number one for me. Reasons being, bios are always great, easy to use, super stable. and they seem to last forever. I still have an old P5W DH Deluxe my mother-in-law uses by simply swapping out the Pentium 4 with a Core 2. Asus supports there products for what seems like forever too. I had no problem flashing the bios, putting in a processor that honestly, the board came out way before the conroe line came out, and that computer works great. Love asus.
My Asrock board is impressing me so far. Not as robust on features as asus, but seems to have good quality, good driver support on the website, and was super easy to set up. My ram and processor clocked out perfectly from the very first turn on. Very impressed.
EVGA I feal makes some decent quality, but they don't seem to support their boards drivers more than they absolutely have to. My 780i sli was a good board, but windows 7 drivers were impossible to come by, and there really shouldn't be any reason not to have had some.
Finally, biostar. I've had good luck with them in the budget arena. I feel their bios was pretty terrible at first, but lately that seems to have improved pretty good. I'd never first choice a Biostar, but for a low budget system, I feel they do a great job, especially today.
What do you guys think? Let's get some more REAL WORLD experience here.
