Hello everybody! (Please excuse my noobyness, as this is my first post)
So I recently got a second GPU so I could crossfire them to play battlefield better.. (XFX Radeon HD 6770 1gb DDR5) They are both identical cards, btw.
Ever since adding the second one I have had nothing but problems. The first time I launched BF3, I could run on 1080p on the ultra preset and have around 60fps. Now all the other times I have run it I cant go past 35fps on high.. BF3 crashes now pretty frequently, and sometimes even windows. When I am able to play, It is very jumpy and I get a lot of lag spikes pretty often. I have crossfire enabled in CCC and on AMD system monitor it shows both are being used to about 80-98% Since then I have reinstalled windows, reinstalled the drivers, and everything else I could think of. Do you think I am bottle necking somewhere? I'm thinking that my PSU may not have enough power for everything too... (530w0 Any help would be GREATLY appreciated!
