Intel comes up with great products although they price it out of reach. Hence, I've always found the AMD platform to provide a much better price-to-performance ratio. The value that an AMD proc gives is complemented by its affordable chipsets and mind-blowing but at the same time aggressively priced graphics cards.
Intel might have great processors in the high-end, but they never were, at least whenever i ventured out to buy,competitively priced in the mid-end or the low-end.
So, considering the entire platform whether it be the bleeding edge, entry-level or the mid-end, AMD makes more sense.
Here's a comparison on Tom's hardware on this:
