    on very intensive graphic games like, crysis warhead, my FPS will drop to 4-7 FPS for 5-10seconds then returns to normal. I'm running 10.3 mobility drivers. same thing happened on my second M17x with 4870 CF. I never had any issues with my First m17x with GTX260m SLI. it feels like the graphics card downclocks for a few seconds. Temps are good, 71C highest. i can't figure out what's going on. I ran 10.3 preview drivers and dell drivers. same issue. could it be hardware issue?

    I'm interested in this thread too.

    You hear all the time abou the M17x slaughtering crysis but I'm yet to see it.

    The 4870's are great but I think theres bound to be a driver issue or something somewhere.
    Can anyone confirm a benchmark on 3D mark vantage for a 720QM 4 gig 1333mhz RAM + dual 4870s?

    I scored a 10,500 which I THINK is a little low?? Shouldnt we be pulling around 12,500 at least?

    1) Make sure you have the latest BIOS version.
    2) Check your FPS while the CF is OFF. If the single card runs fine it might be your CF cable or the secondary GPU.
    3) Is there any difference with vsync ON and OFF?

    that is the correct score. the it 720qm is suppose to get the same score as a Q9000 overclocked to 2.4.

    crossfirex turned off, FPS is big. I lose 30%. vsync off, same thing. bios is the latest.

    might be throttling due to heat. can you monitor the temps of both cards during games ?

    well. i paid a lot of money for my laptop and if it doesn't run like it should, then i don't want it. i have 2years complete care so if dell doesn't want to help me figure it out, i'll just break it so they'll have to replace it.

    Yup I agree with you. I'm just using throttlestop as a temporary fix; maybe by chance a real fix will be released(but I don't have my hopes up). So I am planning to get it exchanged for a new one when I have the time to spend hours on the phone. ~
