Dual monitor question

[CmoAMD]

Hey my friend told me that if you have dual monitors, that the extra screen is still being processed off the video card... which sounds right. Heres my question.

My computer will be for heavy FPS gaming, photoediting, webdesigning, media PC, and office applications.

I will be getting the 7800GTX 512MB, is that enough for what I need, and running on dual monitors? Should I go SLI? This is what I had planned for my non SLI.

DFI LanParty UT RDX200 Cross-Fire / 7800GTX 512MB

Also plan on getting AMD X2 processor, waiting to see if I get this new job before ordering stuff .

u can try just getting one and see if it is okay if not they get another one for SLI.
