One thing to take into account will be what the laptop will soon be used for. If it will just be an accessory used to check mail, watch movies and surf the web, then those don't go that at the top of the purchase price range and you might probably break free with a 400$ model.
But, if the student involved will soon be needing a notebook to work well with, or demands power from the laptop, the purchase price can go quite high sometimes.
Depending on what part of studies the laptop will soon be useful for, there are a few factors that require your consideration.
A notebook for someone who attends some form of social studies will mainly be useful for writing papers, creating PowerPoint presentations and asus gaming laptop price in bangladesh spreadsheets. They're the average laptops which you will find almost anywhere.
They don't require plenty of horsepower to perform simple programs such as for example Microsoft Word, PowerPoint or Excel.
If the student attends classes which require graphics work or design, then a top end laptop could be needed. If it's graphic design, then the laptop with several CPU core, about 3GB or RAM minimum and a significant dedicated graphic card will soon be required for things to run smooth.
If there's architecture involved or complex 3D rendering, then, again, some powerful CPU, a minimum of 2GB or RAM and a significantly more than decent graphics card that's able to produce a quality rendering to the last pixel will soon be needed.
