I'm just curious as to what iMac would be faster or better for me. I currently use a Macbook but am looking around to get an iMac. I don't really mind which one I get (white versus aluminum) but I do know some of the advantages of getting the Aluminum one. What would be faster of these two? 20inch White iMac, 2.16GHz processor, 250GB HD, ATI Radeon X1600 128mb, 1GB Ram (up to 3Gigs) or a 20inch Aluminum iMac, 2.0 GHz processor, 250GB HD, ATI RadeonHD 2400 128mb, 1GB Ram (up to 4Gigs) I could imagine the White one has a faster processor (as they are both the same processor models... correct? C2D. But the Aluminum one has a more powerful Graphics card. I just want a machine that will guide me down the road up to 2, 3 years from now. They are both speed upgrades compared to my 1.83GHz MacBook.
