I used to be squarely in the Intel camp. I believed, at the time, that AMD was not ready for prime-time. For a long while now, though, I have been using AMDs.
I do not see that changing any time see. The price/performance ratio for the AMD's still seem to be superior to Intel and I have had no real problems.
One interesting thing to look at is a recent comparison C-Net did on the dual core processors for both AMD and Intel. AMD absolutely destroyed Intel. It was no contest. This makes me thinking moving forward that it makes sense to stick with AMD. I plan on building my next computer as a dual-core platform, so I do not think I have a choice but to go with AMD.
