a friend in secondlife helped me with some settings in secondlife and that really helped, got me to where I wanted to me FPS wise. Hitting 70 FPS, depending on the sim and how many people on the sim, so I am how I want to be now. Now that I have some good settings for secondlife, I am going to throw the 6970 back in there and see how that fairs against the nvidea and see if ATI really isnt that good for secondlife. Spec wise the 6970 2 gigs should be a better GPU then the 560 ti, so we shall see what card I keep, then come monday I will be selling my 5850, either 6970 or 560 ti, and the 5670 that came with my XP3 8300.
Been interesting getting my computer to where I want it to be, but I do know no from experience and hands on, that the way to go is building your own computer. Working inside that case that came with my dell was tight and limiting, as well as costs more compared to what I could have done building from scratch.
