How seriouslly should I take SLI Anti-Aliasing 64x?

[leandrodafontoura]

Im on a GTX 650, but Im planning my next build.

I've hear of SLI-Antialasing of 64x if you pair 4x nvidia cards in quad SLI. I tought that this was simply 16x anti-aliasing made by 4 diferent cards, with the image quality beeing the same but with more frame rates. Or is the Anit-alising 4 times better? Is this fake advertizing?

*Imagines 64x MSAA*

Any setup would be utterly destroyed by that. Antialiasing above 4x supersample is pointless because above that your essentially seeing the gaps between the pixels, 4x to 8x is also a pointless, you need to break out a magnifying glass to see any difference.

SLI doesn't combine graphical processing capability per frame, it just makes the cards render alternating frames. You don't gain any visuals, just framerate.
