Some basic questions -- SLI vs Crossfire, SSD vs Sata (?)

[Sam DeathWalker]

Well if you use 2 monitors you might consider two video cards, again as stated not in SLI or Crossfire. But still I would go with one really good one.

Not sure if you can use 2 video cards if you only have one monitor.

My site has good information on it, as far as recommened multibox systems, (did you see my new post on a 48G no texture lag system?) so I refer people there like I would refer them to Intel's site or Tomshardware. Plus there is a really good write up as to the Killer NIC and how to set your nvida video card to maximize for wow (from the nvidia site).
