Out of interest, what graphics hardware (i.e. screen(s)) will you be playing on, and at what (total) resolution?
An SLI setup of that power is massive overkill for most screen setups and resolutions, and will cause problems with drivers, heat, noise and cost more to buy and run. You may well be better off buying a single high-end card (I'd suggest waiting until the new Radeon HD 69xx series comes out in November and see how they are and what happens to prices) that can potentially be SLI/Xfired later.
Sorry for the double post, but what monitor would you recommend?
