I have a gaming machine/audio machine and I'm finally putting down some money for a Mac Pro (as my dedicated DAW) and keeping my PC as a gaming/internet build. I'm looking for a reliable KVM switch (a switch that allows me to have one monitor display, yet have 2 computers hooked up to it simultaneous so I can switch back and forth but leave them both on). I currently use a USB mouse (Razer mouse, mainly for gaming) so that might be a problem, and I a PS/2 keyboard (which I will probably get a new one anyway.) Can someone recommend a good switch, any problems, suggestions or comments about DVI vs VGA or USB vs PS/2. Thanks!
