I've been using my Dell M6800 nearly daily for about 18 months; it has been a great performer - no problems at all. I purchased from Dell configured with an Intel i7-4940MX 3.10 Ghz / 4.0Ghz turbo CPU; 32Gb DDR3-1600 RAM; NVidia Quadro K4100M; 2 500Gb SSD Drives.

I use it at my desk with a docking station, and drive 2 Dell 27" 4k monitors at full 4k resolution, 60Hz.

I'm not a real geek, so I don't run any benchmarks, etc., but this laptop works fine for my uses: Adobe Photoshop, Lightroom, Premiere Pro, Audition, Media Encoder, the MS Office Suite, multiple browser sessions, Visual Studio (sometimes multiple versions running simultaneously for different projects); SQL Server, SQL Server Management Studio, dbForge mySQL Studio, IIS, Topaz Labs, WinPCap, WireShark, etc., etc.

I had one problem with the setup: it turns out that the Dell P2715Q monitors require a certain BIOS rev level in order for the NVidia card to run both of them full resolution at 60Hz. Dell engineers worked with me, and finally isolated the issue, and sent me two new monitors with the correct BIOS rev, and it's been fine since then.

The built-in display (upgraded to the full HD matte screen) is fine for normal work, excluding extensive photo and video editing. For coding, general office applications, browsing, it is fine. Battery life is good as well, I get 3-4 hours.

There were many options available when I ordered; essentially, I could pick nearly every component and configuration option I wanted. I replace an M6500 with this, and am happy with this upgrade.

 >:( This laptop is piece of scraps. secondary vga amd always disappear on device manager. you can not do anything without resetting bios (unplug every power and bios battery). Can not fit in standard laptop case, because of sharp rectangle shape. Performance is fine but secondary vga is problem.

The comment that the Dell M6800 is available to individuals in 'pre-configured' only, is incorrect. One has to navigate around the normal 'individual' interface. I know because I have purchased, and am presently using a Dell M6800 that was not a 'standard' configuration. I have also purchased previous Dells that were supposedly only available to Businesses. It does have a fingerprint reader, contactless and contact based smart card, touch screen, runs the i7-4910MQ 4 core processor and an Nvidia K4100M graphics card w 4GB of texture memory and has the red metal case. I am also running a 'hybrid' drive (SSD/disk combination). The only thing with going around the pre-set designs is that the wait time is longer (because it is not a 'stock' item) and there are no financing options.

If I wanted to, I could have gotten a full 1TB SSD, 32GB RAM, and a even faster CPU and a K5100M graphics card. I do miss the 1394 interface that was on previous Dells though. My film scanner uses a 1394 interface. I have already UEFI dual booted the machine (Win8.1, Fed20) and am looking at ordering an SSD for more 'tinkering'. It is possible to get an SSD from non-Dell sources and use backup/restore or in my case, I used a Fed20 - Security Live disk to manage the partitions.

Maybe the presets are only available to those outside the US, but I suspect it is possible to navigate around them.

I have the m6700 and use it everyday with 3x 27 HD monitors from the docking station. This unit is a workhorse and i travel with it between work and home.I have never had such a good pc/laptop before. Now i am considering the m6800 but dont know if there is any point to upgrade now that i see the review. My advice if you do buy one, make sure it has full size ssd in the main hard drive bay.

"Overall, 90% of the sRGB color space are covered, although the possible colors that can be displayed (over 893,000) are quite close to the figure the sRGB color space offers."

I asked what exactly the model of screen installed in this laptop. LP173WF1(TL)(B3)
or some other? Screenshot of the program HWiNFO is very would help :)

Hi, I have M6800 for 4 months and discovered the following ISSUE, dear owners of M6800 with Nvidia confirm please that you have the same problem I have, or write that you don't have, many thanks !!!

1) Dell Precision M6800 laptop (Intel HD 4600 graphics, Nvidia Quadro K3100M),
   switchable graphics (Nvidia Optimus technology) is disabled in BIOS;
2) Windows 8.1 Pro x64, all firmwares, BIOS and drivers are the latest versions, all latest windows updates
   are installed (I performed a clean OS installation, then installed all necessary drivers, then installed
   all Windows updates, no additional software were installed);
3) I always use "Maximum Performance" power plan with the following settings in its section "screen":
   -- turn off display (on battery: 10 min, plugged in: 15 min),
   -- display brightness (on battery: 85%, plugged in: 85%),
   -- dimmed display brightness (on battery: 85%, plugged in: 85%),
   -- enable adaptive brightness (on battery: switched off, plugged in: switched off);
4) There is uniform dark grey background on the Windows desktop (this background might be any other
   dark color, uniform or not, without any bright areas).

Display brightness changes in spite of the adjusted settings in active power plan. The problem exists
in two cases only: (i) I work on battery; (ii) transition from battery to mains or vice versa. In case "i"
display brightness increases when a bright object appears on the uniform dark grey background of my Windows
desktop (for instance if you run notepad.exe and its mainly white window appears over the desktop) and
display brightness decreases when the above bright object disappears from the uniform dark grey background
of my Windows desktop (for instance if you close or reduce to the taskbar the notepad.exe window). In case
"ii" display brightness decreases when you pull a power connector/plug off the laptop and increases when
the connector/plug is plugged into the laptop again.

This issue does not have a place if switchable graphics (Nvidia Optimus technology) is enabled in BIOS,
and the laptop screen is driven by, I assume, Intel HD 4600 graphics. As I utilize on my laptop
10-bit color depth workflow and correct color reproduction, it's much comfortable to work without
switchable graphics. I tried all latest video drivers, from both the laptop manufacturer web-site and
Nvidia web-site drivers including their latest beta-drivers, but the problem exists regardless of
the driver version installed. There isn't the problem under Windows 7 Pro x64.

I'm also on my third M6800 from Dell. Every single one has had a graphics card issue and port issues. The first M6800 had three nonfunctioning ports and a graphics card that just up and died. Dell's solution was that we ship it to them, they fix it, and they ship it back in oh six weeks or so which isn't what the warranty says they'd do.

They finally shipped a replacement that was slightly better than the broken one, but still broken. It took weeks for them to finally agree to take it back and send a not broken one and they only did that because I harassed them on twitter about it.

The third one rapidly blinks so much that it's a wonder someone doesn't have a seizure when starting it up. It again has broken ports and Photoshop doesn't work on it. Their customer service is pretty disappointing ... just like my laptop.

- Does not work OOTB with any linux, because of the BCM4352 wireless hw. So you must replace this with Intel PCIe half-card.
- Make sure you have the wonderful 3-year Dell warranty.
- Pity the drives are not as easily removeable as other systems, still, I had to buy this because I could not find any equivalent spec: 32G RAM, at least 2 swapable HDs.

I think there is something wrong with the rating the M6800 received, how come there is a 89% rating in Games performance and only 68% Application performance, this does not make sense at all ... how do you calculate the rating? I found the M6800 to be on of the fastest of laptops and I just think there is something wrong in the review about this

Overall, 90% of the sRGB color space are covered, although the possible colors that can be displayed (over 893,000) are quite close to the figure the sRGB color space offers.

This is incorrect. First of all, the sRGB color space does not define any number of colors within its three primaries. sRGB defines the chromaticity coordinates of its primaries. The number of possible colors which a laptop panel can produce is defined by the color model the system uses. Most PCs use the RGB color model with 24-bit colors (8 bits per channel) which means 256 colors per channel. The total number of color in this case is 256^3 = 16777216.

In this case the panel can cover 90% of the sRGB color triangle. Whether or not the panel can produce larger color gamut than the sRGB, the number of possible colors is always dependent on the color model.

Please correct this.  ;)

i think the m6800 is overprices.  I can easily find MSI Mobile Workstation with better specs at cheaper cost.  Also, MSI has 3K display (2880x1620) models with Raid 0 built in.  They ported over their gaming technology into the workstations to boost up the performance.  I understand Dell has been in the mobile workstation game a bit longer but there are other options where you can get a lot more for what you pay Dell for..
