It improved similarly to the 7970, I think. I'm running 7970 CF which is basically the same as the 7990s out there, and I'm seeing 5-15% improvements across the board in performance, which is really awesome.
I'm just super excited I can play The Witcher 2 with ubersampling at long last... that was half of my excuse to buy a second 7970 and I've been really upset that it wasn't working
Also @James888 - thanks for the tips! Didn't really mess with my hashrate (still @ 1250 MHash/s) but it reduced the level of artifacting I'm seeing. Didn't get rid of it completely, but definitely reduced it so that it's less annoying.
Also, my 2 cents about the clocks - I'm not experiencing any problems... cards clock themselves just fine at idle 2D and at load. Maybe it only affects reference 7970s?
