so i just did this and thought i would see a decent increase in performance... but there rlly isnt a diff maybe 3 fps. Should i uninstall the driver and reinstall them? I didnt touch them cause when i put the other cards in the system enabled crossfire itself and everything And both cards listed as running the same driver (the one i installed yesterday). If anyone else is runnin crossfire 270x cards please chime in... The cards r an msi and sapphire vapor-x both OC edition and OC set to 1160. Both cards prior ran excellent alone at 1160gpu clock and FPS in bf4 look pretty much the same on the same settings (ultra settings 43-55fps)

Stupid question but do you have the crossfire bridge on.

2 270x's in crossfire should do min 61-max 100 fps in BF4.

Of course always take into account that benchmarks are usually on single player and single player vs 64-player multiplayer always give different fps, multiplayer always being lower.

And also, what motherboard. Some downgrade PCIe slots to 8x/4x when two cards are in because they are lower quality boards.

Do you have the cards connected via bridge? I'm running two 270, but I am mining rather than gaming. What is your motherboard? Check to see that the PCI-E slots you are sticking the cards in are running @ a full 16x. You will get lower performance if they are configured to 8x speed. Try running furturemark to see what frames you are getting.
