First time poster...long time lurker here. I am a long time Apple lover...but a long time PC owner. For years I have wanted to buy a Mac...bought one for my wife but never for myself. Well that time is going to be this summer to buy a Mac. Coming from the PC world I just haven't jumped into to seeing how different hardware is when it comes to Mac. So I started digging around to try and get more information about the new iMac 2011 with the 2nd gen intel chips in there with a 6970M video card vs a 2010 MacPro and 5870 video card. What I really wanted to know was personal experience with members who have one or the other in terms of performance. Are the new iMacs faster than MacPros or vise versa and if so how and why? I also come from a PC gaming world so that has always been something I look towards in terms of raw power. As I continue to drift away from gaming, I want the availability to play games if want at high resolutions, yet have the ability to work on photo and perhaps video editing, as it is something that I have always been interested in. Having said that I know that a refresh could be coming for the MacPro. I know that Intel has the new xeon chips out there. Given the keynote recently, it seems that Apple might be moving away from the idea of a desktop but who knows when that really would be. One thing to note is that I do like the idea of being able to expand a little and the new iMacs are going to be rough to do that with, besides a RAM boost. Could anyone share there thoughts on what advantages there are with buying an iMac vs MacPro. Thanks again in advance and I am glad I finally took the time to post!
