Hi,
It depends what type of memory your Sapphire 9800 has?. . . .if it has
Samsung 3.3ns or lower (3ns/2.8ns) then yes it will reach *Pro*
speeds (and above). . . but if it has Infinion memory then you will
have problems!. . . .
BTW: I use a Sapphire 9800 and its so good I didn't even get around to
overclocking it yet
