well, I think i know a thing or two about these two forums.
as you mentioned that "GPU Fourm" is actually refers to '显卡' . at first is a graphic card forum provide by tieba.baidu.com, which then became a place that a lot of people discuss computer hardwares in china.
"Tualatin Fourm" is actually refers to 图拉丁 another forum provide by tieba.baidu.com, people also discuss hardwares here.
as for tieba.baidu.com you can think it's like reddit in china .
these two forums often came out some funny rigs，and whimsical ideas, which definitely make you laugh .
like shoe box case or radish radiator……
