I've already ordered my iMac (specs in sig) but was just comparing it to the Mac Pro and found it comes quite close in terms of price. Only reason i went for iMac was it had everything i needed and i was fed up with ''the tower's' that i had with all my PCs. Including my education discount the base Pro is about £18 more than the high end iMac (with a GPU upgrade from Nvidia to ATI HD). But the Pro lacks wi-fi and bluetooth, has only a 640GB drive and 1GB less RAM than the iMac. But the main difference is the 2.66ghz Nehalem compared to iMac's core 2 extreme @ 3.06ghz. So does anyone know how much of a performance difference there is between the two processors. Considering the iMac's is a laptop cpu.
