Would have built it in.
But unlike the apple software, there are quite few apps on Windows that use the SSE and SSE2 or the SSE3 extensions (which would be comparable to the altivec coprocessor) and therefor they are not comparable.
Because the usage of the vector capabilities of it etc make a serious difference and thats the reason why 800Mhz G3 outperform a 1.2Ghz P4 that easily (beside its bloated oversized pipeline naturally)
