    I did some 3DMark's API Overhead Tests using my R9 285, both from the GPU and from the laptop (using laptop's panel / connecting monitor from laptop).
    http://www.3dmark.com/aot/42320 (from Laptop)
    http://www.3dmark.com/aot/42321 (from GPU)
    I don't know why Mantle didn't work when connected from the laptop, but I want someone who has Win10 to do the same testing I did, but instead of Mantle, try DX12. It should work on both from GPU and from Laptop.

    Didn't think hiding it would make them so that I'm the only one who can view them.

    I would contact (call) Dell's Spare Parts and Accessories department. They may have one, but it may be costly.

    Had the opportunity to test an evga 980 ti SC+ with my alienware 15 w/ 4710HQ & 4k screen. The cpu is overclocked to 3.5ghz on four cores, and 3.7ghz on one core, when the GA is attached. This evga card has a boost clock of 1190mhz, but my gpu meter was saying it was 1230mhz. Here are some benchmarks just to give you an idea of how the performance is running on the internal lcd, external lcd, and at different resolutions. As Game7a1 has mentioned, it appears the performance loss is significantly reduced at resolutions higher than 1080p. There is a bit more performance loss using the internal lcd. That is due to the bandwidth consumption sending the display signal back across the GA connection, and the inefficiencies of optimus. But that performance loss is reduced as well at higher resolutions and depends on the application. For me, that performance loss is negligible compared to the convenience of using the internal lcd.

    @kakashisensei The difference between your numbers from the internal LCD and external LCD are pretty similar to the difference I see when I use the GTX 960.
    Hmm... I wonder why. The bandwidth on the 13 is almost half compared to the 15 and 17 R2. I'm guessing the bandwidth consumption for using the internal LCD is either the same or proportional on all three laptops.

    Been reading a little backwards, and I can see some still struggle with the amp.
    Is there a issue, or have Dell/AW fixed most of it?
    I'm thinking of buying the 15" Core i7 and a 970m, with a external display ACER pred isp G sync + 980ti,

    How is the noise from the cpu with the amp? And how noisy is the amp itself? Like the fan and the psu?
