Geekbench measures various benchmark scores to rate your machine's speed against others. It's a free download! But the 64-bit benchmarks cost a small fee. Also seems as if the 64-bit version makes the score go up- sometimes significantly. Notice that it doesn't say 'Hackintosh' but my new smbios.plist now spoofs Geekbench into thinking it's one of the new iMacs! Here's a link to my Geekbench results from a minute ago.
