Hy guys. I wanna get a brand new iMac (i7, 4GB+8GB Ram, SSD) in the next weeks. But I'm still not sure about the configuration of the new machine. This iMac will substitute my current machine a desktop pc which is a pretty lame horse (Core2Duo E8400 3 GHz, 4GB Ram)... I'll use the iMac for normal internet stuff, university stuff, heavy lightroom and photoshop work and perhaps once a month some video editing. I'm not playing any games, so this isn't any relevant for me. I'm using my 32" flat tv (1080p) for watching movies via the iMac via DVI-DP... and perhaps I'm using the old 19" eizo screen as a second screen for lightroom work... Should I pay the price for the 2GB graphics card upgrade?
