I currently have a home-built PC with a mid-line graphics card including a DVI out. I also have a brand new Mac Mini (DVI out is standard). My monitor is an old, but very nice, 17" Sony CRT. I'm expecting to want to upgrade to a 17 or 19" LCD in the next year or two, but for now, I have the CRT. I want to be able to control the 2 computers using a KVM switch. I have priced KVM switches capable of using DVI and USB and have also priced those for VGA and USB. The price difference is very significant to me. I don't play games on my computer, but I do watch video and have a large collection of digital photos. Assuming my new LCD has DVI support, am I going to notice enough of a difference to make it worth while to purchase a KVM with DVI capability, or can I save my money and get the VGA switch for use with the VGA connections?
