I have a 15" Macbook Pro (2.88 GHz Core 2 Duo OC'd to 3.06 GHz w/6 MB L2 cache, NVIDIA 9600M GT w/512 MB vRAM OC'd to 9800GT, 4 GB of RAM, 500 GB HD, and removable battery) and I was just wondering whether or not I should sell my old Mac and spend some money to get the new i7 15"... My computer scores about a 6.5 in Windows Vista Experience Rating. I have yet to try it out for Xbench. I bought this computer for a little more than the new Mac is worth (top 15"), just in case that matters somehow.
