nVIDIA and ATi Graphic Processing Units are both capable of running simultaneous Anti-Aliasing and High Dynamic Range at the same time.<br />
<br />
nVIDIA however use OpenEXR (HDR) Technology. However for this to work with Anti-Aliasing it requires that the game has support for its feature sets. Few games do, which is why AA + HDR on nVIDIA cards is very rare.<br />
<br />
There are few other differences between these cards. ATI have put more efforts into Shader processors whereas nVIDIA have put more effort into Processing Pipelines (physical).<br />
<br />
The only other major difference is that nVIDIA GPU's are able to work with OpenGL data much more effectively due to the use of advanced Z buffers <img src="/images/smilies/smile.gif" border="0" alt="" title="Smile" class="inlineimg" />

Games like the HL:2 series i can play maxed out with HDR and AA even though it's made to work on ATI cards better (and im sure it does), but games like TrackMania: Nations/F.E.A.R i can only run at medium/high-ish settings and thats made for nVidia cards lol.
