Widget performance

[Scikar]

I've noticed in the past that turning off XrayShader and TeamPlatter in late game gives me a decent performance boost, but I find the game quite difficult to play without at least TeamPlatter on. I'm using a Phenom II X3 720 and an ATi 4970, and I like to have AA and AF turned up to reasonable levels in most games. Is there a particular option such as line AA that is likely to have a big impact with these widgets or is it unavoidable?
