I like that they have a good selection of processor families, although I wonder why some are missing. For example, SuperH, VAX, m88000, NS32000 all are missing.<p>One thing they could fix is using non-whole amounts for any field. The m68030, for instance, has 1/4 KB of data cache and 1/4 KB of instruction cache. Also, the sources of performance data could have better indications about sources and ways to run tests and submit results.<p>All in all, though, it's a neat resource!
I just bought a few x79 boards for <reasons> and this would have helped me decide my options when plotting out the up front cost vs power savings.<p>Edit: I can't actually view the site at the moment, but my point is pcpartpicker doesn't have _everything_
