I’m not sure why a PC that’s less than 100 percent stable is acceptable, but how many times have you read that someone’s got an incredible overclock that ‘works most of the time’, or ‘is fine unless you put too much stress on the system’? A PC that’s less than totally reliable is as useful as a hammer that only works on weekdays or a car that only starts nine times out of ten. You can probably put up with it, but the thing’s broken and needs fixing.
Of course, the magic ‘100 percent stable’ tag is an elusive one. If the PC complete a run of Cinebench R10
but fails to run Crysis
for longer than two minutes, is that PC 100 percent stable in Cinebench but not in Crysis
