Windows 8 is it's great drawback.
I am able with this laptop to play older titles like modern warfare 3 on highest settings above 60fps, and more high end games such as far cry 3 on medium.

I did not think the problem was so common.

So im a big time gamer and my desktop was assembled by myself and cost me a good chunk of cash, but I needed a portable gaming laptop for the weekends and dont have the cash to shell out for one. This thing is a beast, I dont know how it plays the games it does with the specs that are on it but Ive been playing League of Legends, black ops 2, dota2, starcraft, Final Fantasy 14 mmorpg, world of warcraft all on medium settings with 60 fps, this thing stays cool as can be, and the battery life while gaming straight through is three hours which is falsely advertised but highly expected from anyone who knows a thing about computers. If you are looking for something cheap and will play any current game on the market at medium settings this thing is for you, IT IS the cheapest gaming laptop on the market period! It also does all those boring things like surf web and school project junk ^^ without any stuttering, and can run multiple apps at a time with no lag.

I am just so pleased with this ASUS laptop. I have now been playing and messing with the new laptop as well as the new to me Windows 8 which overall is not that bad once you get the hang of it. As for the laptop I did my studying before jumping in and buying a decent priced laptop. I decided to go with this laptop due to the price, specs, and having dealt with ASUS with my Nexus 7 which everyone knows was incredible for the price. I was shopping around for a few days before making my mind up on this laptop. I am very pleased with this purchase. I tried a few games already just to see how well the laptop can run the games right out the box, and I am pleased. Far Cry 3 runs great, as do a few other PC games I tried out. Just please keep in mind this laptop is not made for gaming so do not expect some of the newer games coming out to run on maximum settings. The speed of this little bad boy is incredible. The pc has yet to really heat up or make a noise this is after hours of use at a time. The laptop seems really well built. The keyboard is very responsive. Also I was very surprised at how great the screen looks for being only 720p, plus very please at how loud the speakers are for this very overall well put together laptop. The laptop also looks and feels great. I would not try it but I am sure it can take a fall or two. I paid 450 and I honestly if I had hands on prior I would not have mind paying a few hundred more, yes it is really that good. Anyways if your looking for a great laptop for a great price you have one here. Enjoy!

This is a good machine for a great price. It has a fast processor, a ton of hard drive space, and a huge display. It also comes with a free 1 year warranty which covers fixing or replacement of the machine even if you drop it or get it wet! The outside of the machine is made of some sort of slip proof material, instead of the shiny plastic that most laptops are made of. It looks a little weird at first, but I think I kind of like the look of it now. It's different. The keyboard is huge and has a number pad, which is a huge step up from my last laptop. The webcam isn't great, but will suffice for Skype chats. One of the USB 3.0 ports has a more snug fit than the other for some reason. I've tried using it more often than the other in order to possibly loosen it up a bit. The port works fine though. You just have to use a little more force when connecting or disconnecting a USB device. Battery life could be better. It will get a little over 5 hours unplugged, but I only use it home so that doesn't really bother me.

The only thing that I didn't like about this computer was the Windows 8 operating system. It's very weird. It's like Microsoft only wanted to half commit to an app based interface while trying to keep its original identity. I felt like my computer had multiple personalities. The interface is not intuitive at all, especially if you're upgrading straight from Windows XP like I did. There is no start button. You have to place the mouse arrow on specific parts of the screen in order to accomplish tasks, instead of just clicking on a button or icon. Thank goodness Asus included a "tutor" button to teach you how to use these different features. The app interface portion looks unpolished and the app selection isn't great.

The laptop itself is a truly amazing product. I was fortunate enough to purchase this laptop whilst it was slightly cheaper, but even now the ASUS K55 is an incredible "bang for your buck." There are absolutely no regrets towards purchasing this laptop. Unfortunately I have come across a small issue regarding the screen, and have no clue how it was conceived. This laptop has been under my care for at least two weeks, all the while furiously curb-stomping any task I have thrown at it, but for some reason the screen has started to fail on me. The top, roughly 1/6th, portion of the screen is completely incapable of anything other than emitting a funky grey or yellow color. I don't know if I had placed the laptop in my bag incorrectly as I was packing during the morning, or if some other nuance managed to take advantage of me. Also, even though I would LOVE to have this replaced, apparently it is not an applicable option.

So with that, I will warn all possible customers to be as careful as possible with the screen. Other than that, this laptop is a magnificent product for whatever you may need it for. It is incredibly fast and responsive, and will dominate any task you throw at it. If I were able to get a replacement, and not have to settle for a refund, (or the screen itself didn't give out on me) this laptop would definitely have had received five stars.


Fast and Responsive A8 quadcore processor
Very suitable large hard drive
Hard drive is also double partitioned (C: & D:)
Beautiful 720p graphics
Battery life is decent

The screen is either very weak, or mine was defective
The mouse pad takes a little getting used to

Windows 8 is confusing at first, but I don't see any of the 'major' issues others come up with. Personally, I can dwell in the desktop portion of the OS and go back to the home screen whenever I want to look at stock or other feeds.
