Daft Question time . . .

I'm running 1333Mhz @ 7-7-7-24, does 2000Mhz @ 7-9-7 timings improve fps performance in games as well as other software? with 890FX?

I did check with a 790FX using 2000Mhz 9-9-9-24 OCZ Blade sticks a year ago at various timings but all results didn't make even 1fps difference only fractions.
