Alienware's M18x, Part 1: NVIDIA's GeForce GTX 580M in SLI

A pair of NVIDIA GeForce GTX 580Ms may seem a bit excessive for a 1080p screen, but at least the screen itself in the M18x is a fine entrant. Unfortunately specific details about the panel type are hard to get; Alienware and Dell have a tendency to obscure the panel model number in the system in ways we can't really get through. Thankfully the only screen option available for the 18.4" M18x is a good one.
It's not taking the prize for "best notebook screen" away from a monster like HP's DreamColor IPS panel, but for a 1080p TN panel the M18x's screen gets the job done and is at least able to handle the lion's share of the sRGB gamut as well. The panel seems to be performing fairly well if closer to the middle of the pack in our comparison here, but keep in mind that the panels we're testing are largely the best of the best, with only the mediocre 1600x900 screen on the Toshiba Qosmio X775 being a real offender.
Viewing angles aren't spectacular, but they're still more than adequate for a TN panel. 1080p really is the way to go for a notebook screen if you can get it and thankfully, with the M18x, you can.

What about the case?I believe the m17xr3 is plastic.
The m18x has an aluminum case. I actually own this with 6790 CF. This one was of the deciding factors as I have own the m17xr1 and m17xr2. When I saw the r3 had a plastic case much like my m11xr1 with cracking hinge problem, I decided against it. Didn't want to talke a change on cracking hinges again. Probably not the case, but an aluminum case feels much more solid.

The M18x's case only has an aluminum plate on the lid and aluminum trim, at least as far as I can tell. I honestly didn't find the build quality to be radically different enough from the M17x R3 to merit mentioning.rsandoz - Tuesday, October 4, 2011 - link
My main cause for concern was the "after 6 or so months factor". Does the m17xr3 have a cracking hinge issue after 6 months. I had an m11xr1 and after 8 months the hinges cracked internally. Felt like the ultimate hooptie laptop. Plus the plastic case has more scratches on it than my m17xr2.Death666Angel - Monday, October 3, 2011 - link
Seeing how this is pretty much a desktop in most terms, I would like to know what kind of PSU is shipped with the unit. Also, could you provide power consumption while gaming/stressing the system with the different setups? I'd be interested in the difference between the nVidia and AMD GPUs used here. :-)Otherwise, a good review and a monster of a laptop. Nothing for me though.

Buy the Core i7-2860QM instead it has same base clock with higher turbo boost and a 10W lower TDP for $500 less.JarredWalton - Monday, October 3, 2011 - link
That doesn't make a review "meaningless". The TDP is simply maximum power; in most loads you won't hit that level. As for saving $500, sure, go for it, but remember you'd also give up overclocking of the CPU. If you're already willing to spend around $3500 for this sort of notebook, what's another $500 to boost CPU speeds from 2.5GHz base and 3.6GHz max to 3.5GHz base and 4.2GHz max. With GTX 580M SLI, you'll probably actually realize a performance improvement from the CPU overclock in games.Ushio01 - Monday, October 3, 2011 - link
Sorry I never meant the review was worthless in itself just the out of date CPU.JarredWalton - Monday, October 3, 2011 - link
Understood, but I'm pointing out that the overclockable CPU might be worth the upgrade price, at least if you're willing to spend this much in the first place (I'm not). The i7-2860QM has the same base clock, but unfortunately the laptop Alienware sent is using the earlier i7-2920XM instead of the newer i7-2960XM. Either way, the XM model CPUs will get you unlocked multipliers and the ~$500 28x0QM chips won't.aznofazns - Monday, October 3, 2011 - link
I'm not sure you'd run into any significant CPU bottlenecks with a stock i7-2860M, though.The argument that the $3500 already spent justifies the additional $500 for the unlocked multiplier doesn't really make sense. The $3500 is a sunk cost. It's already gone and shouldn't affect the decision to spend more on the CPU.
The real question is... what is the marginal benefit of the 2920XM over the 2860M? Would you really be seeing significantly higher framerates? I'd say probably not. The dual GTX580M's in SLI would still be the bottleneck for gaming at 1080p, unless I'm mistaken.
