Buying a computer is like buying a car, lot of variants come to play and you have to consider all of them, like it or not. If not you can end
up with a computer which not as functional as you expect (at least for your needs) at the end.

We suggest you to write down the purpose you’re going to use your computer one by one.
For example; keeping some text data, watching movies and videos, surfing on the internet, playing games, to maintain your business, for homework, using a software like photoshop, power point, AutoCAD or Quickbooks for your pictures, presentations, designs or accounting, etc.
Now all the computers do all of these things, but some of them do some these thing better than the others depending on their specs.
For example you need a powerful video card and a fast hard drive (7200rpm NOT 5400rpm) for playing games, or you need a lot of memory and fast CPU for making a design or working with graphics, etc.
You definitely don’t need less, but more is not going to be a problem.

And after all of these you have to consider the price of course. Don’t forget all computers are designed for to do a wide range of things, but they can be determined for being better than the other for specific needs or carrying more tasks by being flexible than the other models.

Never forget even the most trusted brand or model might malfunction.
All of these products are mass production at the end and a mistake might happen to all of them. How they handle it matters the most.
Everyone of us has a chance to became a victim to the weakest link….
