AMD's have in my case, rock-solid stability and reliability and the NVidia chipsets beat the problematic intel chipsets left and right.
I'm running a dual opteron and dual athlon mp servers here with uptimes over year without any glitch.
My home machine is now AMD64 (AthlonXP being phased out) with Asus A8N-E and zero problems whatever.
What I hear from the Intel guys is that you have to upgrade your motherboard almost every time they do an upgrade. Not mentioning all the fiascos and problems with the consumer chipsets. The best example being the new dual cores come out. If you have intel, yet another 'replace the motherboard and get a bug-ridden new chipset on the same go'. AMD, just upgrade your Socket939 bios and you're set.
No bias here, I used exclusively Intel until Athlon Thunderbirds came out, they just offered the better bang for the buck. And after Opterons came out, I just had no choice but to chase the Xeons out from the server housing since they were just no match for the Opterons.
Things are by the way bit less interesting on the server side now, intel is catching up. If they have better product, I have no qualms about buying their stuff again
