It also depends on configuration and version of OS. For example, tuned slackware 12 kernel will outperform untuned generic slackware 12 kernel, which will be on par with unapgraded(i.e. fast) 5-year old winxp in terms of overall performance (but with better gui responsiveness), which will vastly outperform Ubuntu 9. Something like that. It also depends on hardware - 40-wire IDE cable may mysteriously prevent you from enabling DMA on IDE drives (only on Linux), which will make any windows machine perform better with HDD-intensive operations.
If you have a lot of free time, you can spend your entire life fiddling with various performance options, versions of software, but as far as I know, there's no decent "perfect benchmark" that would measure overall
system performance to assist you - you'll have to see/check yourself. There are several (that were already listed) for specific tasks, though.
