Overall its game of : Budget and Requirement.
Depends on what u wants it for. Graphic and gaming computer mostly focus on the GPU and CPU.
Office computer mostly need a good range CPU and ram and not focusing on the GPU.
Sound editors and musicians focus on the Sound Card.
Auditors focus on how big the screen is.
It also depends on the Brand and the Software u want to run.
So find the reason then choose wisely.
I should ask first myself
What is the purpose I want from the computer
then computer options are based on the answer, that's it
the most important thing is for how long this computer will be up to dated and keep still with technology devolopment every year .
in another meaning for how many years it can be operate ( no need to buy new computer every year)
needs
For me this how I decide which computer I need to buy or provide the user.
1. Who will use the new computer?
Graphics Artist Employee
2. How they tend to use it?
For Designing purposes
3. What application he needs to run on it?
Adobe Illustrator CC
Adobe Photoshop CC
4. Application Operating System Requirements?
Both applicaiton can run on Windows7 with Service Pack1, Windows8, or Windows8.1*
5. Application Hardware minimum requirements?
Both applicaiton needs the following:
Processor: Intel® Pentium®4 or AMD Athlon®64 (2GHz or faster)
RAM:1GB of RAM
HD:2.5GB of available hard-disk space for installation; additional free space required during installation
Video:1GB recommended with1024x768 display (1280x800 recommended)
6. Budget?
Base on my budget I will try to find a computer that meets the minimum or recommended Hardware requirements to run those application that the user needs to run on the new computer.
If I have a big budget where I can afford to buy higher performance computer more than they need ill buy it base on the importance of the user, user application and computer use.
If I need to buy computer to a secretary I will med level computer that can handle MS office or other kind of office application they will daily open.
Note: Remember there will always be a higher application that will come out anytime with higher system requirements so when you’re buying new computers think2 or3 years ahead on time.
It really depends on usage and type of application we need to run. If you want to do some internet browsing and document writing, you need to get something low specicifcation and cheap, but if you need it for high grapgic performance or intense math calcualtion or software development, you will need higher ram, cpu and diskspace. Also, you have to consider budget vs computer power.
the first important thing when purchasing a computer is the memory (RAM ), you have to look8gb memory if u want to have a hi-speed pc , then second is a quad core processor
