I stopped using my Crossfire 7970's months ago before the "magic" drivers were released. It seems that HardOCP agrees that SLI still feels smoother despite the Ghz bios and the magic upgrades in performance. From http://www.hardocp.com/article/2012/12/04/gtx_680_vs_radeon_hd_7970_multidisplay_showdown/7 Admittedly the 7970's beat the 680's in FPS, no question about it. There is something wrong with AMDs crossfire implementation however, it shouldn't produce so much stutter. I wonder if their additional frames are coming from choosing stuttering to get better benchmarks. Its the sort of trade off they might take to win but which negatively impacts their customers.
