Here is the iMac I have my eyes on. It's $1799. 2.93GHz Intel Core 2 Duo 4GB 1066MHz DDR3 SDRAM - 2x2GB 640GB Serial ATA Drive NVIDIA GeForce GT 120 256MB How does this handle the Adobe suite? I'm worried that if I get this, I'll want to soon upgrade to a Mac Pro, and so on. Does anybody have experience with Macs and 5DII video files?
