first is the firstname.lastname@example.org second at 3.4ghz
I'm a little unhappy to be honest ( with the increase, the cards are GREAT!), maybe I've to ramp it up a bit...
Well, for my part that's what I was hoping to see, a decent bump in score from the CPU overclock. As I shared earlier I was able to get around 32k with two actual 470's in SLI w/my chip at 4.0, so I was hoping your score was lower just cause of the CPU being at 3.2, and it looks like that's exactly what it is. If +700 points results from going 3.2->3.4 it would seem that 4.0 would put you right around the 32K I was expecting assuming these cards truly work just like 470's.
I'm impressed that the hit to the score was so small from moving the 2nd card to a 4x slot, <1000 gpu points is really not bad for such a move, esp in a situation that's already CPU bottlenecked.
And if I've said this once, I've said a 1000 times ... it's time to retire Performance mode in Vantage around here
. High or Extreme is SO much less prone to bottlenecking it's not even funny. Why any of us care how such mighty cards do at 1280x1024 is just beyond me.

Actually it's totally logical ... it's what happens when the test is too easy for the GPU(s).
Vantage Performance with 2x465's is running so much faster than that test was ever designed for. Remember it was made years ago now, to test like 8800GTX's and such. Now with two monster fermi's in SLI, the framerate is so high that the CPU can't keep up, i.e. the cards are cpu-bottlenecked at the Performance mode settings (1280x1024, 1xAA, etc).
In Extreme mode, you'd get the very close to the exact same GPU score with an i7 at 2.66GHz or 4.0GHzEdited by brettjv - 8/9/10 at 9:25am
