alright let me clear up a few things,first of alll, yes i am using an sli setup, it's MSI 256MB 6800GT's and they are extreamly quiet, My case, cm stacker, has alot of insulation, and the only noise i get it from the exaust fan. Drawback's eh i wish, how bout runnin far cry on very high seeting,s with fill AA/AF on. Or Half Life 2 on full setting with high framrate. Power compusition, nah, who care's wow and extra $5 on ur hydro bill per year, if u picked up 2 pennies every day, u could make sum money in the process. Cost, a lil bit expensive in retial, buh price match helps alot, avalibility is the only draw back if u ask me.. None of the current stores carried that parts i needed in stock, so i ahd to order online from ncix.
