As some of our readers pointed out after we published the initial review of the Core 2 Duo E8000 series, the benchmarks are not yet optimized to take advantage of the SSE4 extensions. These will allow the processor to accelerate certain functions related to content creation or processing. However, SSE4 support depends on applications, and there hasn't been enough software available to justify spending more time on the subject at this point. We'll look into SSE4 once it will begin to make sense from a software-support standpoint.
