I'm looking for extension can display articles in tabs and filter categories like this site
www.videogamer.com/#all

Hey,

you can try to do this with Gavick Tabs GK5 alongside with Gavick News Show Pro GK4. If you don't like this you can try using JoomSharper SP Tabs with SP News Highlighter.

Altho they are not AJAX based they might suite you well.

Hope this helps.
