It was probably merged into this thread: http://www.nvnews.net/vbulletin/show...threadid=19894
We have stickies for a reason, people.
And before anyone brings it up, I will do some pre-emptive explaining. The [H] review thread was not merged because it was already big, and the discussion was more about the [H] review/reviewing methodology than the actual cards reviewed. It later turned into a Tom's Hardware thread, and obviously if this thread was merged it would fragment the discussion and lead to confusion. Hence why it still exists as a separate entity.
If a thread is big enough or specific enough it will be allowed to live on its own. If it is not varied enough to merit a new thread it will be merged into the main discussion.
