It ain't no Blue Waffle special for sure.
I guess the point here is that what you offering is of no use to gamers as-is, and non-gamers wouldn't care about the "only measurable using software" improved performance aspects of it vs. something older/slower/cheaper. Your target market seems to be somebody who wants to use it for parts to build it back up to a gaming box, and a lot of those guys are wary of buying somebody's overclocked/overheated hardware. They are also into the "artistic" nature of the build like Mr. Waffle so them buying fugly hardware is unlikely.
Bragging would be me telling you that I am writing this on my i7 17" laptop with AMD FirePro M8900 Mobility Pro Graphics 2gb video - while I am also using my i7 15" laptop w/ 2gb video along with my new to me/purty/cheap/old technology desktop that is now connected to my dual 28" monitors. But that would be rude.
Sorry for suggesting you lower your price and explaining why I thought so. Was just trying to help.
The price he is asking is fair, only thing I don't understand is how he got away with a 250w powersupply.
