Sudden low fps

[IX3 SAINT 3XI]

hi there just a quick question, ive been running my 5770s on crossfire for a while in crysis 2 usually getting around 55-60 fps.. 1920 by 1080 on a 61htz 32 inch lg tv.. which was an improvement from a single 5770... but the past few days ive been getting around 35-40 fps on crossfire from same game and same settings. im finding that i get the same results if not better disabling the crossfire support, ive swapped the gpus around but still it seems that one or 2 of the 5770s are underperforming compared what they used to ? i have the latest catalyst centre and crossfire support but cant figure out what the problem is ? many thanks

You could you post your spec's including your PSU brand and wattage? Some times it is a heat problem that causes fps to drop. Also it could be the type of game your playing with certian settings.

Are your drivers up to date? I really need to know if your are monitoring your temps? if so what are you using?
