    Hello every one! I install a second 5870 card in my m17x r2 and all worked well (especially with the 240 watts power supply that came with).

    But there is one thing: my game (like Next Car Game: Wreckfest) isn't able to go to 30 fps. Yeah I know that driver is probably the reason. But damn these cards are running under 50% from what gpu-z say. The CPU do not go more than 50% of it's power.

    My config is:
    16 of ram (need to know on which clock they work)
    720qm processor
    2x at I radeon 5870
    250 GB ssd
    1400*900 display

    Any tips to make these cards work good?

    Why is your resolution so low?
    Are you not on 1920x1200 RGB display?

    Is that the only game that you have tried? There may be issues with the Crossfire optimization of the game.

    Well after that I looked at the GPUs realtime information ( GPU-z), I saw that the game is using all the dedicated RAM of the GPUs (2 GB in my case). So yeah maybe it is the game. I played Dying Light on th same laptop and the result seem "good" (I know that it is a recent game and that 5870 becoming old these day). Anyway if you have any advice I will take it for sure. Thanks
