Well, I have a 8600 GTS right now and will be upgrading, but I also have a spare comp that will be using it, however, there's a problem I believe.
On tomshardware, it showed that OVERCLOCKED editions of the 8600 GTS only hit 65 degrees C under load, mine idles at 60 degrees C.
Under load, I have hit 84 degrees Celcius.
I am also now starting to get a lot of artifacts during some of the games I play (UT3, World in Conflict, AoC).
Should I RMA it back to Dell? There's still a warranty in place.
