    Crossfire GPU below. Seems I really need to roll back my drivers, they were recently updated via. Mr.Fox's procedure... CCleaner / Drive sweeper etc...(Not a real driver specialist though).

    It seems people with systems almost identical to mine are getting about 1k higher numbers... Any thoughts/idea's?

    Thanks

    Also, it's worth mentioning that HwINFO64 fan's were not enabled, that was just system temperature monitoring.

    Well it looks like crossfire is working correctly, you are getting almost prefect scaling with the gpu score and combined score. Those score are pretty much on point for your system as well, you might squeeze a few hundred point more with better/different drivers but the people getting 1k higher then you will be overclocking their graphic cards, so I wouldn't stress about your drivers.

    It shouldn't make much difference using the stock fan profiles seeing are you are not overclocking/overvolting.

    I am not really sure what is going on with the second card sensor reading in hwinfo64 though, maybe the sensors are no good or hwinfo is playing up for some reason. Aside from trying a different version of hwinfo and reinstalling drivers I would re-paste your cpu and both gpu's just for peace of mind if you cant get the sensors reading properly. You have 85C as a max temp for your cpu and primary gpu which is not dangerous but I think your system could do better (unless you have a warm ambient temperature)

    Just wondering, how does/did the R9 m290x sit in the lineup? Was this above the 770 but below the 780? I am surprised at how little information about the M290x equipped A18's is actually out there.

    Thank you so much for the assistance. I think my system could do better as well considering its in a very very cool basement when I run it. I will be repasting it and possible upgrading to 980M if it's possible. I see after some brief research it may not be possible with the r1 mobo. Depending on how much gaming I do I think think the 790m SLI combo may be my best bang.

    Again, the assistance is welcomed. I don't understand why my driver are saying they aren't recommended... People seem to do good on th chart with 14.1 drivers but I can't seem to find the download anywhere... And I'm not the most familiar with drivers. One thing that can be said simply by the test is that my CPU is held way back by my GPU it's crazy.

    Yeh that's about right, if you cant find any info on the R9 M290x just look up the 7970M or 8970M as the are basically the same card (so close its not funny). There is limited info on the m290x because it is so mediocre, the 7970M did well, but like any thing people are interested and talk about new and cutting edge tech, not 2 or 3 year old rehashed gear.

    Your welcome.
    Yes that is correct the 980M is a no go with the R1, you will not be disappointed with the 780M SLI!

    The note saying your drivers are not approved is not something to worry about unless you want valid results for bragging rights, competitions or simply validity. Its a 3DMark thing that means if a driver is approved they have checked it to make sure that you haven't tweaked the driver to your advantage for a better score. They don't check every driver so some will always return "invalid results" There is nothing wrong with an "invalid" driver so long as it performs well. You might have to try a few drivers to see what works best with your setup.

    Haha, you got that right the 2920xm is no slouch even today :D

    If I didn't have the 2920x performing so well right now I would consider a new 18 with two 980's... But I have a pretty reliable PC compared to most people's issues from what I can see. I believe I will go with the 780M SLI but I'm just a tad scared of it not working properly or doing something wrong. Thank you for explaining the driver situation.

    For switching the video cards do I have to do anything with bios etc? If it's just removing drivers, changing cards / heat sinks and repasting I'm confident. If it involves anything more than that I'm not so experienced...

    The 780M's are straight forward like you have described, its the 980M that has been the issue in Alienware systems requiring special bios settings
