Well, the first 2 years are usually fine irregardless of make. The problem of cramming all that into this form takes it's toll in time and you may see repairs in years 3 and later. So we would have to define what you mean by reliable. Inherently Windows is unreliable so there's that.
I am trying to decide between two laptops; the Alienware M14 & the MSI GS70 Stealth. From the reviews that i've read, both are highly recommended but I'm having a difficult time coming to a decision.
The Alienware M14 model that I've looked at includes:
16 GB DDR3
1TB HDD + 256GB SSD
14" FHD display
Nvidia GT765M 2GB Graphics Card
Approx Cost: $1850
Whereas the MSI has the following specs:
16 GB DDR3
1TB HDD + 128GB SSD
17.3" FHD display
NVidia GTX860M 2GB
Approx Cost: $1700
MSI GS70 offers more value for the money (better graphics card + larger display, though half the SSD), but Alienware is... well, it's Alienware.
How reliable are both machines?
I am not a hard-core gamer, and I only see myself trying out the occasional games though I will most definitely be installing games such as Call of Duty or BioShock. My main purpose is getting a robust machine that will be powerful enough for my programming needs. I am a .Net developer and most of the time have more than 4 or 5 instances of Visual Studio running simultaneously on my machine... Along with that, I install the Standard/Enterprise edition on my machine as some of my databases are too large for SQL Express - and the standard/enterprise edition of SQL takes more processing bandwidth. I also use other heavy-duty software including Adobe Photoshop, Media Encoder (for rendering of Videos), WMWare with 1 or 2 virtual machines, etc.
Based off of my requirements, I'm considering both the MSI and Alienware as both are seemingly powerful machines but since neither are available locally in my country (Pakistan), I am having the machine purchased and delivered from abroad by my brother who's coming to Pakistan end of this month. I know that these are gaming series, and I sort of love that about them. For this money, I couldn't find a better deal... Especially considering both options have SSDs and Quad Core i7 Processors. (HP would've cost less, but I've had bad experience with HP in the past... and Dell XPS 15 is within my range but since it costs somewhat more or less the same as the Alienware 15 or the MSI... I'd rather consider these laptops over the XPS)
Which machine would you recommend?
