The only reason I keep touting this is because there has yet to be a group of people who actually claim, and
can prove, that they truly see any significant increase in performance while using SLI/CF. In helping people
troubleshoot multiboxing issues throughout the years, I have run into numerous people who have had SLI/CF
enabled, and disabling it has always fixed any issues they've had. This is just in my experience and could of
course be different for others yet many agree with not using SLI/CF.

I have yet to actually figure this out 100%. While WoW natively supports using different monitors (prior to that
it could be accomplished through Inner Space), in my quick test with two GTX 570's I was unable to get WoW
to actually use any of the second GPU's VRAM. I will be honest that I did not test this as thorough as I possibly
could have before I just opted to get a much stronger GPU instead.

I really like the performance side of this option, but I started boxing one toon on my desktop with another running on the laptop next to me and moved away from that as soon as I could; I don't really want to go back to what for me is a less intuitive setup.
People use software KM's (KVM w/o the V) to accomplish using a single mouse/keyboard between multiple
machines at the same time. Input Director would be my recommendation if you're able to use Windows on
both machines. If you're running different OS's on these machines then your next choice would probably be
Synergy although many have reported that Synergy can act up at times while multiboxing.
