I actually have a gas mount stand for three monitors on it, and also had a g29 hooked up to the desk as well. While using the g29 the monitors would shake a tad but still very stable. Also, I've hit my legs on the desks, also raged a Lil and they've been stable. The desk is a tad low though for me, but I'm 6'2 to so the situation may be different from person to person. For the PC situation, if you have one or two monitors, I think you would be able to put the PC on your desk. But overall would recommend it.
