Have some random thoughts... I've only used 5D1 and own a 7D for reference.
If you have a "decent" AF system do you need the viewfinder? I was underwhelmed by the 5D1 when I bought it. I didn't mind the AF, as it was similar to the 50D I also had before. But the extra points on the 7D does make it a little easier to AF without recompose. For shallow DoF that can help prevent focus errors, although you're still limited by the AF accuracy. Going full frame to me is mainly to achieve shallower DoF than is easily attainable on smaller sensors. When I got it, I found I didn't need it after all... it ended up being too shallow for my uses. So I didn't end up keeping the 5D1 for long.
Ill suggest thinking a little more and try sorting out what are the true *needs* and what are only *wants*. See if that points you in the right direction.
