Do I waste the first card and go for a better single GPU or do I risk wasting more, albeit a smaller amount of money on a SLI setup?

Sorry to be the bearer of bad news, but SLI doesn't increase your available video RAM.

I'm not exactly sure why, but i think that if cards use split frame rendering they render half of each frame, but they need to store the entire frame in each card's memory.

When they render alternate frames (eg, card 1 renders frame 250 and card 2 renders frame 251) the same holds, because each card has its RAM filled with an entire frame.

You do have double the video RAM but you also use double, so there is no gain in available memory.
