So, I was wondering, as I am getting an Eyefinity build this summer, will I need 3 active adapters (1 for all screens) or just 1 active apater? I was also wondering if DVI-I connections fit into SL-DVI, because if not then I will have to buy another cable together with my current selection.

Well first, if you are going with AMD/ATI cards (Eyefinity) it's called Crossfire, not SLI (that's nVidia).

Secondly, you would need an active adapter for anything past your two DVI-D ports. Currently I have a AMD 6750 and I have both DVI-Ds (one is HDMI, cause one DVI-D and the HDMI share the bandwidth) and then the display port used. Only the display port needs the active adapter.

Oddly enough, I purchased a Saphire "active" DisplayPort to DVI adapter that isn't powered... so I don't know what they are doing but it works! ... and a hell'a lot cheaper!

I am going with a Gainward GeForce GTX 580 card (http://www.gainward.com/main/vgapro.php?id=432). If Eyefinity is only for AMD/ATI cards, does nVidia then have something like eyefinity for their own cards or...? I mean I can change to ATI card, I do actually have a backup for that.
