the main thing to keep in mind is that a decent system: a64 3000 and above, 1 gig ram, and 6800gt or ultra or x800xt or xt-pe can run any game out right now, including half life 2 and doom 3 at 1600x1200 everything turned right up, 4xaa, 8xaf and vsync on. FPS games are the most system stressful out there. And its a safe bet that most of the new fps games coming out over the next year that you will want to own will be based on the d3, or source engine. So SLI really is only going to be usefull if for some reason you feel the need to run at 1600x1200 with 8xaa and 16xaf, why I don't know

as at 1600x1200 , aa doesn't seem to make much of an impact. But I'm sure for some people this does matter

. I guess when quake 4 is out next year, I may not be able to get aa on it too, but I think I can live with 1600x1200 high quality and 8xaf on quake 4. I doubt I'll miss aa too much :roll:
