Same here, thinking about the 4gig ver's.
But I would really like a 660 with 4 gigs, the performance/wattage would be unmatched.
Probably not no good for 2-4x displays but good enough for a single display, 3d wise.

Now that i think about it, 192bit...
What was it, 32bit or 16bit per ram chip?
I don't think..., if the 660 is truly 192bit, then it's not gonna come with 2gigs.
It might be 1.5 and 3gig configs.
3 gig would be ok for me.
