I like Ars Technica for most things but also visit ZDnet for reviews and using their price comparison engine to find the best deals for hard and software.
I used the Ars Technica system guides to choose most of the parts for a new PC I will be building next week with my 12 year old Son. I respect their unbiased opinions on everything. That is to say, I don't think they are influenced by advertizers.
