i have this exact problem with my cards im thinking its down to power saving features ive owned a few xfire rigs in total and never had it but ive recently updated to the 7 series my self after buying my 2nd card i noticed in CCC and msi afterburner i was gettin no temperature readings and also the bus interface thing u were on about in gpuz i also pulled my rig apart switched 1st and second cards around but to no avail it still does it .Doesnt affect x fire cause as soon as i strt a game the 2nd card kiks in and reports temps and a 2.0 bus interface needless to say i think its the power saving features on the card effectivly down clocking the card/cards to save on power

my specs are as follows

amd phenom II 965 @ 3.4ghz
8gbddr2 800 geil black dragon dual channel
samsung spinpoint f3 1tb hdd
