I just got this board last week. Generally I like it alot, and I have considered a couple times that I might have done better with the K8T800, and the only thing that keeps me from buying VIA is my past experiences with their drivers.
The Nforce 3 is a brand spankin new chipset which definitely bears consideration, but I do not seem to have as many issues as many people on those boards mention (I was checking them out myself today). I have version 2.0 (12/02/03) of the Bios, and may be upgrading soon depending on the resolution of my only issue which is the following:
I ran it for the first week now with 1GB of OCZ PC2100 DDR 266 @ CL 2. It screams. However, it will take DDR400, and I just got my first stick of it last night. It's Corsair XMS PC3200LLPro, the fastest DDR400 I could find that was in stock (shakes fist at mushkin). The system reboots over and over after post, and gives no errors about a bad stick of RAM like it does with a couple bad DDR33 sticks I had laying around. I am hoping when I go home tonight, I can up the RAM voltage bit by bit till I find a voltage this apparently power hungry RAM is happy with. I will try to remember to post back here when I find out. I might also try using the 12/19 bios, and see how that goes.
Apart from that, the Digidoc software crashes on my OS so far, other than that I love everything else this board offers, and besides not being able to OC the RAM and CPU FSB seperately, there is nothing else I could ask of this board. (except cool and quiet support, which as I understand it no one offers yet)
I will try to pop back and let you know, and apart from that I can only hope there's a bios release soon to address some of the issues other people have had with the board recently, and to add Cool and Quiet support, because that would put the icing on the cake for me.
