I am currently running a Celeron 366@550 on a Asus P3V4x motherboard. I was planning on upgrading my CPU to the P3 800E CPU soon, but I am having problems with my motherboard. If I have to replace my motherboard, I am thinking about going with AMD instead of Intel. I like the fact that the T-Bird 900 is a good $30-$50 cheaper than the P3 800 and I presume it would be faster. Which motherboard is considered the best/fastest Thunderbird motherboard out there and why? I would be using my existing PC100 Micron CAS2 memory, so factor that into the equation. I would also be using my 45GB ATA/100 hard drive and an ASUS GeForce SDR video card. Any info would be helpful and thanks.
