I need to decide between these two models. I could upgrade the 2010 4 core to a 6 core later, so that is tempting. I do a lot of audio work. Video wise, I need to dual output to a monitor as well as an HDMI to an large LCD, so a decent video card is required as well. Not sure about the GT120. I have read about upgrading to the 5770 or 5780, but maybe it's worth it to just start with a 2010 4 core. I will also put at least 8 gb of ram in the machine. Advice appreciated! Thanks!
