Well at 1920x1080, typically at 16x aniso and 8xS AA I get nearly identical results SLI or not, heck, removing the SLI bridge doesn't change the result so either 16x slots are coping without it or SLI ain't working/the cards aren't communicating past the 'SLI is enabled' control panel tag.
The only app. I've found so far that does show a diff. is that fur benchmark by ozone3d.net or such. It shows almost double results with SLI. That it's so much though leads me to think SLI just messed up it's counter and it just doubles up it's count for a 2nd card present.
Know anything besides 3dmark that's a reliable way to see if it works or not? I've tried so far:
crysis
ut2004
nfsmw
3dmark05 and 06
and probably others I forget.
this is under xp sp2 btw, though I'm pondering a move to vista 64bit. (odd logic, they already fixed the 2nd card not communicating issue I seem to have under XP, maybe I need to invert my situation to fix my inverted problem ;) )
