Just because upping the 2d clocks resolved the issue doesn't mean that it was the primary cause for the problem. Think about it, if the 2d clocks were the true cause of the issue, then why are there so many people that don't have a problem with leaving it at stock? The answer is the same as when CrossFire would crash my old computer a year ago unless I lowered the 3d clocks below stock - it was because of a faulty part, not the video cards or video card drivers. Just because someone has something listed in their specs other than what they claim to have, doesn't mean they don't own one. A lot of people have multiple computers, and some people don't always update their specs on the go. I fall under both categories.
