@ Buck ... back to the SLI issue. I wasn't challenging you, just wanting to know if you had experience with SLI, as you came across pretty certain about not recommending it - which is fine, as that's your opinion.
I've been using SLI for about 3 years now. I like it, but wouldn't necessarily recommend it to everyone. nVidia drivers work pretty well, but there is still some tweaking that needs to be done for certain games - once you figure out how to set it up, it can make some nice improvements when running at higher resolutions and all the goodies set at high settings. I think I also enjoy the tinkering part of it.
With the power of today's video cards ... even the 8800 series, let alone the upcoming ones, SLI is probably overkill for most. I found that games like BIOSHOCK, S.T.A.L.K.E.R., and COD4 all ran wonderfully with just one 8800 GTX.
I will do SLI in my next desktop, and will no doubt put a 3rd card in there just for kicks to see how it works.
Peace.
