SLI Setup

[Franco_cov]

I have currently got a XFX 8800 ultra card if i was to do an SLI do i have to get an dentical card or can i just use a card with in the 8 series ?

And what are the additional benefits I can receive when I set up an SLI rig ?

Many Thanks

so if i get another 8800 ultra from the same manufacturer (xfx) if the part numbers are slightly different meaning slight difference in speed can i use that to sli or is that going to slow down my ther card ?
