I am a strong supporter of AMD, because their products are typically less expensive than are Intel's products, but usually can provide comparable performance for a lower price. However, to say that one company is overall superior to the other is rather harsh and unfair, in my mind, as I am certain that each company can provide products that shall meet the needs of their customer. My current computer has an AMD Phenom II X4 945 processor and an AMD Radeon HD 6850 video card, and both function very admirably for my uses; I play games only infrequently, but I do watch movies and television series frequently on my computer, and its CPU and GPU are more than sufficient for that purpose.
Of course, I am certainly aware that AMD is faring poorly in comparison to Intel at the present time, so I am very much hoping that they can return to providing strong competition to Intel, as they are the only other major manufacturer of CPU's in the world and thus the only entity preventing them from having a complete monopoly on the CPU market. I do hope that their next line of processors, the FX-based "Piledriver" processors, are better than their "Bulldozer" processors and thus provide better competition for Intel's products.
