The system bus is generally irrelevent unless your memory clock speed is as fast as it is. Since the memory clock speed is 233, the bus speed of 400 or 533 will both take full advantage of it. Regardless, though, I agree that the extra $35 is well worth it for the gains.
One of us is confused
I didn't see anything in the linked article we're talking about that mentioned what speed or even type memory was being used. And change in bus speed isn't irrelevant in analyzing their claim of 10% speed increase. The only way that you could get that big of a jump between a 2.4 & a 2.53 is by comparing 400mhz 2.4 to a 533mhz 2.53.
Anyway, here's a nice article from anandtech that gives the lowdown on the impact of the fsb increase. As a bonus, it includes all 3 chips being discussed here in its tests: the 2.4, the 2.4b at 533mhz, and the 2.53 http://www.anandtech.com/showdoc.html?i=1615
The raw numbers won't mean much, but the relative results between the 2.4b & the 2.53 should give you a rough idea of what the performance difference will be in the 2.4 & 2.53 Sagers.
