Yes they will.
Except they'll both run at the lowest speeds.
So if one is say 500/1500/1600 and the other is 480/1400/1500 they'll both run at 480/1400/1500.

Hmm... I'm not sure. But I think I heard that cards can be SLI'd as long as it's the same model.
Anyways, there's no "primary" card. The two work together.
Perhaps someone who knows more could chime in.

Yes. The latest ForceWare drivers allow pairing of cards from different manufacturers. For example, you can safely pair an XFX 8600GTS with an EVGA 8600GTS.

This is not recommended, so it would be better if you could consider the answer as a “noâ€, but it is possible using CoolBits. Though at the end of the day, if you currently own an 8800GTS 640MB you should purchase a second 8800GTS 640MB. However, when using CoolBits (value set to 18), you can force both of the cards to use the lower of the two memory sizes and operate together in SLi mode. When dissimilar memory sizes are enabled to work together the effective memory size for each card becomes the smaller of the two memory sizes. So an 8800GTS 640MB paired with an 8800GTS 320MB would operate the same as 8800GTS 320MB SLi.

Enableing CoolBits;

Step 1.Click on your Start Menu in the Windows Task Bar and select Run. When the command box opens, type "regedit" (without the quotes) and press OK. With the registry editor open, go to HKEY_LOCAL_MACHINE SOFTWARE NVIDIA Corporation Global NVTweak (expand the menu using the "+" expansion buttons to locate this menu item). Click on "NVTweak" in the menu. Next, right-click on the empty space inside right window and choose "New>DWORD value". Name the value "Coolbits" (without the quotes).

Step 2.Within the Registry Editor, right click on Coolbits and choose Modify. Change the Value data to "18" (without the quotes) and click OK. Exit the Registry Editor.
