Hi, I'm going to buy new Mac mini for web development and digital photography processing using Coda, Lightroom, Photoshop, no need for 3D or video processing. I'll connect it to external display and my 42" plasma for watching HD movies. Should I go for model with 6630M or spend money on 8GB of RAM and SSD? For connecting it to external display I'll use mini display port to DVI (later on, after upgrading to 27" display, mini display port to display port) and to 42" plasma over HDMI cabel. is that OK? P.S. this would be my first Mac so I have many questions.
