Say if im at 50fps just looking at one spot. Then looking around and drop to 25fps. Would say that's a bottleneck? Because my 2nd PCIE 16x is at 4x mode?
I have two 5805's and a crossfire Asus motherboard. Well it didn't work... All my games would lose FPS like TF2 playing at 20fps. So i then brought another CrossfireX motherboard and it worked! Well it worked for half a week and then i got the same problems as the last motherboard. No fps boost, TF2 at 20fps the only game that is still working is BC2 and give me a 30fps boost.
