True. SL looks like shit and graphics are indeed not topnotch, but the performance differences between the two competitors were high enough for me to stick with one (though keep testing the other from time to time). Google it, SL has been known and it's pretty much common knowledge it runs better on eg nVidia, then AMD/ATi. But yes, for other applications, such as Fallout 3 you mentioned, has indeed chance to run better then on nVidia equivalents. Anyways. For Second Life, as Daymian wanted to know, from my experiences with the HD3/4000 series and GF9,GTX series... it runs smoother on nVidia.
