I foresee AMD going out of the CPU business within long, if they don't change their act.
Their last few CPU releases have been extremely lackluster, and they've spewed out advertisement that's been so false I'd label it as lying. Check out Scalis
posts on AMD, he's got the stuff pretty well covered.
In the past, at least the AMD CPUs were cheap - they didn't reach the performance levels of Intel CPUs, but the equivalently performing Intel CPU would be more expensive. With AMDs latest CPUs, they've priced it about the same as Intel's, but perform worse.
A shame, really, back in the initial AMD64 they whooped Intel's hineys... but then Intel introduced Core2, and the rest is history.
