nevermind found it! It's DRICONF
http://dri.freedesktop.org/wiki/DriConf . I actually think it works with other cards besides ati! I guess that's why I couldn't find it since I was looking for a "radeon gui tool for linux". This is great since it probly works for 3dfx graphic cards as well! I have a voodoo 4 4500 with a zalman heatpipe and later to add ramsinks that i'd like to bench! Also works great in real-mode pure dos for running carmageddon in 3dfx mode! Other games are still great with that card under windows 9x like resident evil, final fantasy VII, etc.!1one
It'd be nice if someone also knew a simple binary download for ati overlock 0.3 for ubuntu. It's a simple gui frontend for over-under clocking ati cards using rovclock as it's backend.
