system specs

cx 750w psu
standard Seagate 1tb hdd
x2 asus r9 270x 2gb

increase in what? a benchmark or game? can you be specific?

try reinstalling graphic driver then enabling crossfire again. Turn off VSYNC in CCC and in whatever game you are playing.
Turn up fans and make sure case fans have a good pull/push airflow, as crossfire will increase heat a lot and the GPU will throttle down
