Intel Pentium III 1.13GHz (1133MHz)

SPECviewperf has always been an Athlon fan, and even the overclocked BX platform running the 1.13GHz Pentium III can't outpace a 1GHz Thunderbird. For the most bang for your buck in professional level OpenGL applications, it seems like the AMD Duron with a fast enough graphics card (GeForce/GeForce2 GTS) should do just fine.

The DesignReview viewset tilts the balance in favor of the Pentium III as the top two clock speeds take the winning two positions, both of which happen to be on overclocked BX platforms as well.
