Got a mac pro 2.8ghz 8 core with 16gb ram and 8800GT card. Ran xbench against my new 2.8ghz 24" iMac. Imac scored 178.45, Mac pro scored 177.88. WHAT? So I ran an encoding test. The mac pro finished 30% faster but still, thats not that much faster for having 8 cores. What gives? Is the mac pro just hype???
