The VGA cable actually needs to go from the output of your 2D card (either a non-3Dfx card or your integrated graphics) to the input on either of the 3Dfx cards. Then your monitor gets plugged into the output on the same 3Dfx card. That allows the 3Dfx card to pass the 2D card's signal through when not in use (remember that the 3Dfx Voodoo 1 and Voodoo 2 do not handle 2D graphics and require a separate video card for that).

No need to connect the 2 3Dfx cards together on the back, as the SLI cable takes care of that.

As for the 3Dfx card touching your daughterboard, I wouldn't expect it to present any problems, but you never know. It looks like it's just touching the edge of the card, not touching two components together, so I bet it'd be fine.

Rowdy!! Ok thanks. Any idea on question 2?

Sorry forgot about question 2, I updated my post just now.

Well, it is SLI, but means something different (Scan Line Interleave) than the nvidia one, with the same initials, however.
The monitor needs to be pluged on the same card the pass-through cable is plugged, no matter which one.
Both memory upgrade and memory from the nearby 3dfx card will get hotter this way since both dissipate heat and will exchange it, you better move one of the cards to a different slot if you can.

Thanks a lot guys.

trist007, You may try to change the layout of your PCI cards to prevent them from touching each other if you feel like it, but I see no problem here.

If you are still worried about the two cards touching then just stick a piece of paper where they meet.

Moved the cards around and now nothing touches. Thanks.
