You are just as dumb as he is, then, or a really shitty sock puppet. Screenshots don't mean anything especially with total runtimes counted in tens of minutes, not hours. Even then, I could run for a while and then overclock the cards and take a screenshot before it crashes, whoopie. Regardless, a card with a stock clock of 840MHz, a single fan, and DOESN'T even have a VRM heatsink IS NEVER going to do 690kh/s. The very best 7950's have a hard time doing that, and they come with 1000MHz+ stock clocks, multiple fans, lots more phases, and most importantly a VRM heatsink.
Not even little stick on heatsinks, nothing...
If you had any experience at all with GPU mining with 78xx/79xx and even the R9 series cards you'd realize how ridiculous this really is.
1BTC can buy a hell of a lot more hashrate than 900kh/s, it can buy two 280x cards, a mobo, power supply, and ram. It would hash at 1500kh/s, and it would retain some resale value unlike some $1,000 cgminer config file.
Relax with the insults. I'm just trying to have a discussion here.Not even little stick on heatsinks, nothing...

Anyhow, I've already stated that at the current rates 1 BTC might be too much. 900$ can't buy all of that in all countries (note: it ain't cheap everywhere like it is in USA). Maybe if he recorded a video (10-20mins or more if necessary)? Otherwise I don't know how he could prove it. Stats from pool?
