i think why alienware instead of other laptops for gaming, its simple, alienware is made for gaming, not made to game.
Alienware brings alot of convenience for a gamer, especially one whos not familiar with DIY rig. It is optimised for gaming. You dont need to know how to identify matching processor, graphics card with matching motherboard, you also dont need to waste time assembling the system. Choosing an alienware means a hassle free experience. You will be able to dive right into the pleasures of gaming with it. I may consider getting an alienware in the future if my DIY rig retires. no more researching on the processor, mobo etc. go down to sim lim hunt for it, carry home and slowly assemble. All i need to do is go online, do a few clicks, and just wait for the alienware to be delivered to my place. so much simpler and hassle free!
Performance and convenience aside, the design of the alienware laptop is also very alluring. it is futuristic styling and sleek looking. The ability to change the colour of the keyboard, alien head on the backcover makes the alienware unique and something different even when place with other alienware laptops. I think for this laptop will be a standout if you were to bring it to starbucks to fight with those mbp and mba.
In the past, there will always be comments on how a laptop can never perform well in gaming. achieving 60+ fps consistently on high resolution settings. Personally, i have this problem too. i can never enjoy gaming on a laptop because the components in it are just not good enough to play a game smoothly. I have to rely on my desktop all the time.
However, alienware has changed this, with the Alienware graphics amplifier (AGA). It allows you run a fully fledged desktop graphics card and connect it to your alienware laptop. With this feature, you will be able to hit the optimal fps at high end graphics, just like you are on your desktop. I see this being a really great add on. Again, it is hassle free, all I ever need to do is maybe change the graphics card in the AGA and I will be able to enjoy gaming on high graphics settings. VS a desktop, there is no need for any cable management after the insertion/ replacement of graphics card. The convenience here also matters. Theres minimum troubleshooting to be done, unlike a desktop. It also make your gaming area looks more tidy, less wires, small frame size compared to a desktop. I think it looks really impressive to be gaming on it compared to traditional tower desktops.
Of cause, the biggest concern is the weight. not really that enjoyable to be carrying this around. For me, as a healthy adult male, still ok la, but for a petite guy, female gamer etc, abit difficult la. alienware has been trying to improve on this area. eg. using carbonfibre composite material in their laptops. but i still like to see them continue doing more in this area. if they can just get this laptop to be below 2.5KG, woah, confirm will be a sellout.
