Hi there, I am currently using a mid 2010 MBP (15", 2.67GHz Intel i7, 4gb RAM etc) and I'm looking to add a second external monitor to my setup. I currently have a HP ZR22w widescreen monitor running at 1920 x 1080 and was hoping to add a second identical monitor (mostly cause it would look awesome). I know that the Mini Display Port doesn't natively support two independent external displays, so I was wondering what solutions you would suggest? I've been looking at several graphics expansion modules and I guess my biggest concern is whether or not I need one that has a built-in video card. It seems that most GXMs out there (such as the Matrox DualHead2Go module) are USB powered and use your computer's GPU... while I have no shortage of processing power, I'm using the stock video card (nVidia GeForce 512mb) and I'm not sure if it'll be able to run things smoothly across 3 displays (including the laptop screen.) I don't do a ton of gaming or video editing etc but I like to have the option of playing Starcraft etc without lag. That being said, all the gxms with a built in video card that I've seen are outrageously expensive ($1400+) Any recommendations?
