I've got an iMac, and am going to get a PC for purely gaming. I'm going to use a KVM to share an external DVI monitor, USB keyboard, and USB mouse between the iMac and the PC.

What kind of lag or other drawbacks should I expect when gaming with this setup? Is there usually a noticeable video delay when gaming in this way?

The KVM is little more than a passthrough, so you shouldn't see any noticeable latency, unless it's doing some kind of weird on-chip processing or format conversion. –  allquixotic May 23 '13 at 16:50
    
Okay thanks. Since the PC is purely for gaming, if it doesn't even do that well, then it's pointless. –  Gary May 23 '13 at 17:30
