Excluding any upcoming updates in July or the fall to the iMac line, I'm trying to determine if purchasing an entire new machine to replace my Early 2008 Mac Pro is even that great of an idea. I don't know much about Geekbench, but my 2 X 2.8GHz quad core Mac Pro is scoring 9732 compared to the average of 11478 that the best iMac is pulling. If I popped in a Radeon 6870 (to get OpenCL) and an SSD boot drive, would a complete iMac purchase even be justifiable? What other "real world" improvements would I see when working in Photoshop CS6 and Premiere Pro CS6? Obviously Thunderbolt would be one, but I don't even see myself making much use of that at this point.
