I've generally found the comments on NewEgg (newegg.com) quite useful, when averaged and weighted by the apparent competence of the commentor. I learn details from them that I don't find elsewhere. I'll also look at Amazon and some other places, e.g. anandtech and some of the PC Magazine reviews remain informative. Off topic, but recently I was trying to learn details of the then new or upcoming Intel mobile Core processors. Googling around, the one place that had specifics was a German site. You never know...
