To some extent, I don't really care. I mean, the whole price/performance thing is an issue in and of itself, and it's hard to get a good idea what you're buying, but since actual performance has so many possible factors... If they're about the same power, about the same price, I don't care that much, although upgradability and the availible good motherboard combos are issues. I think I would go AMD for now, just because I hear good things about it
