I know this has been discussed so much but I'm interested in how much your elecricity bill is for your crunchers? My parents just got their elecricity bill and have its over £200 more this quarter than last which they think is the two computers. Is that likely, that seems extraordinary high for 2 PC's (one is an x2 system with a 6800GT, the other a dual xeon with bare essentials, no GFX). Theyre not trying to make me pay for it, im just intrigued as it seems excessively high.
