I don’t think there are enough reviews of the newest offering from Intel to make an entire post, but there very well may be. I’ll start off with what I’ve got, anyway, and it wouldn’t surprise me in the least if there was a section of reviews tomorrow as well, and maybe even the next day. As always, each site’s name is the link to its review of the Intel Core i5-661 Clarkdale.

And to round it out, how about a couple of motherboard reviews?
