Any members used this chip in a system WITHOUT a PCIe graphics card? Intel makes extravagant claims for the on-chip graphics, and I'd be interested in any user's comment. I'm about to assemble an i5-4670K on an Asus Z87-Pro board. I use 2 monitors, do audio and video editing, but have no interest in gaming. I would value any comments, since up until now on-chip graphics have not been worth much.
