How long do you think it would take for this to happen?
I can wait for 7-8 months more, so till near the end of this year
About 1 year as a minimum imo.
I'm interested to see a 680 SLI to 7970 Crossfire comparison, as I imagine the scaling will work to nVidia's advantage.
AFAIK, crossfire scaling on 79** cards is 100%
