Laptops have become a necessity these days. Used laptops are seen as a viable option to own a laptop at a very affordable price. These are the laptops that have been used by a person for sometime and sold for some reasons. Even if the laptop is used for a single day, it is called as a used laptop.

The reasons for purchasing used laptops are many. The main reason is that, it is available at a cheaper rate than the retail price of any new laptop. The availability of used laptops has increased owing to the recycling legislation that makes discarding of old PCs very expensive. Also used monitors are used for photo editing as the CRT monitors provides ultimate color purity than the LCD monitors for editing colors.

When purchasing a used laptop it should both serve functionally and at the same time save money. Doing a little amount of research by comparing and weighing various options from different kinds of sources will help in achieving the aim to buy used laptops at the best possible price. The price of the used laptop should coincide with the features. Internet serves as a good source for searching used laptops.

The working condition of the used laptop is of utmost importance. Normally it is not recommended to buy a laptop, which is more than three years old, for the reasons that either the system would have become outdated, or the user may not be able to run the latest applications and soft wares on it.

The features on the used laptops are the next important thing to be taken into consideration. The speed of the used laptop needs to be checked as used laptops run at a lower speed than the normal desktops with the same processor. Used laptop with less than 128 MB memory is not at all recommended for buying. The screen size, resolution and definition are other important factors in a laptop. Portability of used laptops is also taken into consideration. Laptops these days are getting slimmer and lighter. The weight of the backpack and, accessories should be kept in mind along with the weight of the used laptop to see if it is comfortable to carry. It is wise to purchase an extra battery while buying used laptops as the battery life of any laptop can be only for two years time.

While buying used laptops, checking should be done if it has a wireless connectivity, if not at least should have an external wireless card, since connectivity to the internet and intranet is very common these days. Select the one with a longer range and greater speed.

Check for a USB ports as older laptops may not have them. The more the USB ports the more convenient it is. Also the hard drive of the used laptop needs to be more than 20 GB. The higher hard drive space of the used laptop purchased depends on the budget of the buyer. These days, songs and movies are stored in the laptops requiring larger hard disk space. The most important thing is to buy a used laptop from a reputed dealer so that the purchaser can get a warranty on it.

A graphics processing unit (GPU) is a RISC processor used in video game systems and computers for calculating the graphical output for monitors. GPUs are used at manipulating and displaying computer graphics. GPUs are a part of mother board or they can come along with video cards. Graphic accelerators are a part of GPU also. High performance GPU computing involves solving advanced computational problems using supercomputers and computer clusters. GPU computing includes all tasks that a graphics processing unit can calculate.

In GPU computing the CPU calculations are replaced by Graphics Processing Units. Migrating large scale algorithms and entire kernel onto the GPU co-processors help in arriving at the answer much faster and thus decreases the processing time. GPUs are never a complete replacement for CPUs but complementary. Parallel operation of CPU and GPU has found to increase the performance. CPU’s offload the tasks which are better performed by GPU leading to high performance computing. GPU excel CPU’s in certain computational tasks.

A GPU’s processing power is mostly used while dealing with 3D scenes and video. The GPU computing for a graphics task such as rendering a 3D scene involves many stages like vertex processing, vertices grouping, fragment processing and mathematical operations. GPU computing is also known as General Purpose Computation on Graphics Processing Unit. Acceleration of video and picture editing, artificial intelligence and physics calculations come under the tasks of GPU computing.

GPU uses Advanced Graphics Port (AGP) to communicate with the mother board of a computer. Programmable shaders capable of manipulating vertices and textures are supported by latest GPUs. Very high precision color spaces, over sampling and interpolation techniques to reduce aliasing are also supported by GPU. GPU can process multiple independent vertices and fragments in parallel. Moreover a variety of computational resources are available on the GPU.

Multi-GPU’s are also available and are generally used in high-end home computers to accelerate computer games. Multi-GPU systems use more than one GPU. An example of multi-GPU system is Nvidia which can make a PC perform 250 times faster than usual. Not only that but by making use of the CUDA architecture which is made up ofhundreds of processors cores data set can be easily crunched via the application. General Purpose computing on graphics processing unit uses a GPU to perform computation in applications traditionally handled by CPUs. Additional programmable stages are included to make this happen. The general Purpose Computing on GPU(GPGPU)has cleared new ways in diverse fields like scientific image processing, oil exploration, linear algebra and 3D reconstruction.

GP GPUs are used in computer clusters, physics engines, FFT, audio signal processing, digital image processing, bioinformatics, scientific computing, DSP, neural networks and many more. GPU computing CUDA was developed by Nvidia. AMD has announced a super computer based on GPU which will be built of more than thousand GPUs. This supercomputer will have a computing power of one petaflop. The processing power of GPUs have further increased due to the advent of OpenGL API and similar functionalities in DirectX. Intel, AMD/ATI, NVIDIA and S3 Graphics are some of the players in the market who produce GPUs. Many companies are now engaged in researches to find out the further benefits of GPU computing.

What more could a gamer ask for in a gaming laptop? What game or 3d application do you think would not be running without a snag on the Alienware Area 51 M7700’s 3.8 GHz of hyper threading raw processing power provided by Intel’s Pentium 4 processor? Add Nvidia’s GeForce 7800 GTX with 256mb of dedicated memory for stunning visuals. Not to mention its 4 GB of PC5300 DDR 2 of ram. And of course, nobody with a right mind would settle for less than 7200 rpm for a hard drive given you already have all the previously mentioned top performing specs. Definitely not I!

Oh well, those were the days when all I could do is daydream on getting my hands on the world’s best gaming laptop. Luckily for me, the time for daydreaming is over. Even with our present economic challenges, I have managed well enough to be able to finally get myself the gaming laptop that I deserve.

Dilemma to get Alienware Area 51 – M7700

Ok. Now here is the funny part. I finally got enough cash to splurge on my dream gaming laptop right? So shopping I tried to do. And guess what? Alienware does not sell my dream no more! How ironic. How ironic indeed. I guess my dream will have to remain a dream for a little bit longer – Oh yes! I definitely am not giving up on this baby!

After countless hours trying to get quality information from Alienware’s customer support on how I could get my hands on the Alienware Area 51 M7700, I gave up on the Alienware’s horrific customer service and I took a step back to assess what options I got left in getting what I have dreamed of.

Then it hit me. EBay! There, I finally found one Alienware Area 51 M7700! Right then and there, I almost purchased it outright specially with it’s less than $ 1,000 price tag. Lucky for me I did not let my emotions get the better of me. I checked on the details of the unit being sold by this EBay seller. It does look like it’s in excellent condition; I will give the unit that. However, the configured specs are a little low for my taste. And the worst part? No option for a warranty! Oh no! Definitely not going with that one now. Not unless I want to end up going bald for issues that might arise after buying the rig.

The Solution

Just when things seemed too dark, a light shined at service.ztronics.com. They had some of the few Alienware Area 51 M7700 left on the planet. And not just that. There units are configured even better than how I dreamed it should be years back. And the best part? They have a 1 year warranty as an option. Need I say more?
