<< I have a gts and a le, the le lags like hell! >>
what u mean by "lags like hell!"? I dont notice any lagging for me in games i play (CS, Tribes 2 [low frames though], Tribes, Unreal Tournament).
As for LE or GTS, depends on what you want. I do a lot of 2d work at 1280x1024 and 1600x1200 so i need the higher quality 2d of the Radeon so i'd get the Radeon, but if it's for a gaming system, i'd get the GeForce 2 GTS.
As for "superior support" of nVidia, i'd say the radeon's support is top notch. Drivers work 100%, stability is not a question, and problems are niltch.
