I don't use desktop theme software, MS's windows already burns up a crap load of resources, I don't need desktop theme software using up more, I just patch my uxtheme.dll and then google msstyles, and there is a great site that is like the first or second site, and it has a ton of msstyle themes to choose from that uses MS's Os instead of 3rd party software, but that is just my opinion, with a lot of ram and a really good cpu, you could probably achieve the same thing with software other than the Os.
