Some people have this misconception that when you buy a computer, you need to buy the one with the fastest processor, most memory, largest hard drive, and most expensive video card. This might be the case for some, but it's not always necessary to have a fully functional computer that will last for years to come.
STUDENTS
Laptops tend to be a better purchase for students because of their portability and versatility. When purchasing a laptop, the goal is to choose the features you need without going over budget or sacrificing lifespan. The truth is off-the-shelf laptops are going to have the recommended specifications (memory, hard drive space, DVD-Burner, WIFI, etc...) with the ability to run any office suite or educational software thrown at it for at least 3 to 5 years. That being said, three optional upgrades that will have a direct impact on performance and set your laptop apart from others are: the amount of processor cache, hard drive speed (RPMs), and battery life.
BUSINESS ELITE
The needs of business users are similar to the needs of students. You don't need the fastest processor, or excessive amounts of memory to handle business applications. The version of operating system needed for business users differs from the student or home version due to the necessity of connecting to an office network. Business users should always consult their IT director before making purchases.
GAMERS
Modern-day computer games don't need an outrageously fast processor to run smoothly. If you're going to purchase a new computer or upgrade your current computer for gaming, invest in computer memory and a good video card to increase video performance. When purchasing a video card, keep in mind the human brain can only process about 30 frames per second. Buying a video card that can produce 40 or 50 frames per second may result in overspending and produce unnoticeable changes in performance.
RESEARCHERS / GRAPHICS DESIGNERS / MATHEMATICIANS
If you're doing research or computations, the faster you can process the data, the better. Your processor cache, processor clock speed, and hard drive speed (RPMs) need to be as fast as you can afford. This will allow data to be gathered and processed quickly. Graphics designers and video editors have an additional need of a good video card.
In short, when purchasing a computer, the amount of processor cache and hard drive speed will have the most direct impact on performance, and if you're planning to use your computer for intense graphical applications invest in a good video card.
