Trying to choose my next laptop, but too many confusing informations. Need explanations please!

post #1 of 15
Thread Starter 
Hi,
I'm trying to choose my new laptop, and I found an Alienware M18x for "only" 4 grand (3k euros).
Considering what's inside, i don't think it's all that expensive.

Intel® Core™ i7-4800MQ (6MB Cache, 3.7GHz w/ Turbo Boost)
16GB DDR3L Dual Channel 1600MHz
Windows® 8 (64-bit)
Ecran 18,4’’ (467mm) WLED FULL HD (1080p)
2 nVidia® GeForce® GTX 780M w/ 4GB GDDR5 – nVidia SLI® enabled
64GB mSATA SSD + HDD 750GB / 7200rpm

Here is the link (French site):
http://www.grosbill.com/4-alienware_m18x_noir_-185962-univers_informatique-univers_informatique#0


Usually these days, GTX 780m have 4Go memory each, and not 2. Considering the max resolution on that computer's screen is 1080p, would there be a huge difference in performance between 2 GTX 780m SLI with a total of 8Go memory VS 2 GTX 780m SLI with only a total of 4Go memory?
I read in another thread that the 2 cards memory actually don't add up, so 2 cards in SLI with 2Go memory each don't actually make it 4Go, but instead stay at 2Go... I am not very knowledgeable when it comes to hardware, and i often tend to think that bigger numbers and better, so in my eyes, it makes things even worse.


Here are my questions:
Keep in mind that i'm a layman, so keep it relatively simple, please.

1- Despite the site stating "2 nVidia® GeForce® GTX 780M w/ 4GB GDDR5 – nVidia SLI® enabled", is there actually only 2Go that are really being used? How does it work?

2- What is the difference in performance compared to 2 GeForce GTX 780m w/ 8BG SLI? Would it be noticeable in games such as Crysis 3, and the next to be released Witcher 3?

3- Also, would i have a use for 32GB DDR3 instead of 16 if we take into account that i'll be playing Crysis 3, Witcher 3, other very demanding games and do a lot of Photoshop? Of course, concerning those 2 games, i'd like to have them maxed out (with the exception of AA maybe, i never enable it) with at least more than 40 fps.

4- The SSD size is quite small: only 64GB. With Windows 8 installed on it, how much space left would i have?

5- In general, is there another slot on these rigs to stick another SSD?


One last thing, i'm not looking to be convinced of buying a desktop (cheaper, faster, etc... i know), or another brand of laptop than that Alienware at the moment.
I wouldn't want this thread to go off topic smile.gif


Thanks in advance for your answers!

I'd never pay that much personally, you can build a better spec desktop for bang on half the price, doesn't mean I wouldn't like to own that sexy beast though ^.^

1 - I'd like to think that there would be 4GB per GPU, rather than 2GB but I'm unable to quickly find anything to support that.
2 - If the 4GB version has enough then probably no difference at all. It's the same with RAM, if you don't need more, then adding more likely won't make any noticable improvement.
3 - 8GB would be enough for Crysis 3 or Witcher 3 maxed out though I'd say get 16GB for the sake of it, and if you use Photoshop all the time 32GB might be of benefit, but when you are using it have a look at how much RAM it actually uses.
4 - Based on my experience having an SDD with only Windows Embedded 8.1 and a few programs installed: if you get the 16GB of RAM, after installing Windows you'll likely have about 23GB of free space, and your programs fill some of that, you'll want the OS and programs on the SSD and everything else on the HDD. If you get the 32GB of RAM after installing Windows you'll only have about 7GB of free space, that's before any programs have been installed etc.
5 - It has space for one drive total so you'd have to replace the 750GB hard drive, the 64GB SSD is in a mSATA slot.

I see, thanks.
I'm "worried" about the amount of memory on the cards though?
I definitely need an answer for that.

The Alienware 17 has the option for a single 780M with 4GB of VRAM, so I'm pretty confident that the two 780Ms will have 4GB each, thus 4GB usable.

It might be worth buying from dell itself:

http://www.dell.com/uk/p/alienware-18/pd?oc=n00aw825&model_id=alienware-18#overrides=n00aw825:11~826868;6~GT780D;3~32GB4D;8~2561TB

You get options like:

256GB mSATA SSD Boot + 1TB 5400RPM SATA 6Gb/s
32GB Dual Channel DDR3L at 1600MHz
Windows 8.1 Pro (64Bit) English

Anything after 2GB is a waste for 1080p. People usually just say the whole "Oh if you mod skyrim blah blah blah" well that's a long since passed game and you'll never break 2GB at 1080p.

It's a marketing ploy they use to jack up the prices on the GPUs because 4GB is bigger then 2GB right? Must be more powerful. rolleyes.gif

Also, unless you're trying to max out every game on the market, dual 780Ms is a waste of money. They are exceptionally overpriced for the performance they provide. On top of this, the GTX 800M line just came up. I would wait a bit for the Alienware refresh because as is, you're just gonna pay waaay too much money for last gen tech. Just sayin'.

Also, I'd steer clear of Alienware anyway. Sager/Clevo (If you're UK then it's Clevo) is considerably better for the money. You get more per dollar and overall the machines are built better. From what I hear over at the folks at the NBR forums, the Alienware 18 is a downgrade in EVERY WAY from the M18x R2.

The GTX 880m is a renamed 780m, with overclocked GPU and memory.. According to the reviews, it provides about 10% performance increase, and is even more overpriced...
No thanks.

I'll have a look at the Clevo, though..

I got 30+ mods in Skyrim and I rarely break 1.5Gb vram usage with my GTX 580 Classified 3 Gb.

Well, not gaming only.
I said that i would like to photoshop on it too.
But as for gaming, Crysis 3 and the soon to be released Witcher 3 are ultra demanding, hence why i'd like a laptop like that. Also, chances are, i won't have to buy another one for 4 or 5 years....

Pretty much everybody tell me that double GTX 780m SLI, i7 and 16Go Ram are overkill, but on some of the youtube videos i've seen, with all that power, Crysis 3 in ultra setting doesn't even run at 60 fps.... So perhaps it's not so overkill after all, no?
