Hi All, I have been sitting on the fence for a while and currently have a Core i7 965 Windows machine with SSD and have been flirting with going for a Mac Pro. Some of the things I use the Windows machine for is lots of copying of huge files from SSD to my NAS drive, lots of unarchiving RAR files, some video encoding, downloading huge files that come in at around 2 mbytes/sec, and then general stuff like email, browsing but have all kinds of programs open. I also like the OSX OS but will generally be using Windows 7 for most of the above functions. So mainly using something like Parallels for dual OS. Based on this I was thinking the 12 core 2.93Ghz, a 256GB SSD from OWC and upgrading RAM to say 12GB from OWC. I also have a Dell U3011 30" Monitor which I plan to use. Would love to hear your experiences and recommendations. Do you think I will get any speed benefits with the above system? Is the 3.3Ghz significantly faster? And would the speed and performance be similar to my Windows machine? Thanks guys.
