This is not meant as a slam by any means, but merely a simple matter of observing the scaling properties.
Intel's plan for the Prescott is to ramp from 3.2 -> 4.0 ghz by the end of this year, or a 25% increase in clock speed. Figure that an Athlon 64 to ramp from 2.2 ghz -> 2.6 ghz is an 18% increase. Not quite as much, but only 2 speed grades here...see what I'm getting at? 4 speed grades for Intel as opposed to 2 for AMD.... The higher Intel clocks its processors, the larger the increase to get a performance benefit, and this is assuming perfect scaling. Prescott's little secret not-withstanding, all that little secret really means is that because of the larger cache and other performance improvements, it's going to scale closer to "perfect" than Northwood could.
Is SSE3 going to be a wildcard? IMO, no. SSE2 doesn't even benefit gaming, much less SSE3. If any of the extended instruction sets are going to see a benefit, it's going to be SSE because of single-precision.
