I just installed a Radeon LE 32 DDR in a Duron 800 system I'm building for someone else. And I have to say i'm pretty impressed. Its 2d is excellent, I was impressed by its performance and image quality in D3D.
Overclocking it is definitely worth it, the card would run stably at 190/190 after putting a fan on it. So if you don't mind adding a fan and doing a few tweaks, its hard to beat the $77 shipped price of the Radeon LE.
It's one of those deals that sounds almost too good to be true, but this card is basically exactly the same as a $140 Radeon DDR after you tweak it.
