Eyefinity questions

Anyone here tried eyefinity or know a little about it?

Since I'm getting a HD5970 I'd like at some point to run a 3 monitor eyefinity setup.

I have a 24" Samsung at the moment, I looked at 30" solutions but the price is stupid, I could use a HDTV but the resolution sucks for text, I run my media PC in the living room at 1900x1200 or something and the text still looks like ass at that res, not something I'd like to look at all day.

I was wondering how flexible eyefinity is? Could I run my 24" inch as the center screen, and 2 rotated 17" as the left and right screens? That would be ideal, 3 24" would just be way to large and expensive and I'd be moving my head to much for comfort.
