4870x2 Flicker causing fps drop

Right here it is you may have heard of a similar problem before but mine is well seemingly not fixable...

I recently updated my 4870x2 saphire with 10.10 drivers, however when i did in every game i play after thirty seconds the screen will flicker fps will drop to about one it will flicker again then the screen will go back to decent fps, however the same thing happens every few seconds now and now again. Now from what i can see this is obviously an issue with rendering 3d objects ingame, as it only happens ingame.

So what i did was to revert back to my old drivers and wait for 10.12 to come out. However supprisingly the problem kept happeing even though I had reverted. So I uninstalled the ati drivers, then used driver sweeper/cleaner in safe mode to clear up any old remnents then installed the old drivers once again (while deleting anything by ati last modfied recently as well), but this did no use either and the problem continues. Today I downloaded 10.12, and....same problem once again, the new CCC is good as well by the looks of it but no change to my problem. I read of similar problems other places where they were saying it maybe crossfire so disable ATI catylist, but this did nothing nor did any other setting i changed. I've downloaded ati tray tools as well, and it has done nothing.

So I come to these forums running or ran out of idea's to fix my screen flicker/fps drop. I was hoping maybe invien that someone could shed some light on the situation for me as ati support havent really supported me as of yet. All i can think of now is reverting back to 2009 drivers, or system restore or windows reinstall.

(note my specs are in my sig)
