Moving away from anything ASUS or ABIT back to Gigabyte.
I used to have a GA6-BXDY Gigabyte M'Board that took 2 450 P3's with 1 GIG of 100 MHZ SD RAM which was faster than all of the ASUS and ABit P4's that I ever mounted. Their Chip Sets just seemed to be Too Slow compared to what that Old Server Board would do with a 440 BX Chip Set. It was the best M'Board I have ever used and I'm still hurt that it died. :(
The ABit was out of Desperation after performance issues with the ASUS M'Boards that where just slower than the old Dual CPU Gigabyte unit. I was very quickly unhappy with that one as being the Top of the Range the BIOS was telling me lies without the RAID Option available. At the time there where no replacements available so I just tried to live with it. I've finally had enough of it's strange behavior and have ordered a Gigabyte to replace it with. I know that they work well though even with a Top End Quad Core I still maintain they are slower than that old P2/3 Board.
Besides according to Gigabyte that have twice as much depth of Copper on their Tracks, Ferrite Cores for their Chokes and Solid Capacitors so they just have to be better. :^0
