After reading quite a few of the articles I'm still at a crossroads. I have read the pros and cons regarding a single machine running 5 copies of wow with the biggest downfall being price. The typical cost point for a machine such as this i.e. i7 920, Asus mb, 12gb ram, velociraptors in raid 0, and gtx285 has been around $2500. This does not include a monitor, which for me is not a problem, but even a machine such as this has some people doubting that 5 instances can be run without trouble in heavily populated areas.

The other alternative is using multiple lower cost machines and a vetra. I assume you already have one machine to run wow on. Going with 4 more low priced machines that can certainly run 1 copy of wow each plus the cost of 4 more monitors and a nice stand in addition to a vetra can also be done for around the same price point, $2500 maybe a little less.

The thing I'm most curious about is eliminating some of the monitors and possibly the cost of the stand. By using a vetra with a kvm switch why not just run two monitors? One dedicated to the main and then one monitor dedicated to all four slaves. How long does it take for a kvm switch to show the activity on a screen going from one pc to the next? My spare monitor takes approx. 4 seconds to power on. This is unacceptable for play if this is the amount of time it would take to switch. Does a KVM require the monitor to power down then power up each time it is switched to a different machine?

Curious if anyone has any answers to these questions, thanks.
