I think it's fair to say many people who fold or crunch are always preparing their next upgrade
My 580s are staying put for a while until I can afford a couple of 690s. With two young children and xmas round the corner it will probably be a long while before 690s are in reach.
My next planned upgrade is getting another i7 to replace my i5 and possibly upgrading the 470s to 5 series cards. Mainly for folding/crunching performance but the rig is also used by friends to play BF3.
