From 6 years I am using computer. There are some basic tips that I will like to share while buying a new computer
Mostly buying computers is not a big deal now a days, but there are few tips that I will like to highlight If you dont have much budget try purchasing refurbished computer but do check it for physical damage and ask someone who knows a thing about compuer to take a look at it then buy.
Now lets talk about the processor and other hardware. If you are not a Hardcore gamer then dont take i7 3rd gen processor as mostly the processing capacity will not be fully used and 3rd gen is not much different as compared to 2nd gen. Opt for i5 as it has good processing speed and will run almost all games. Theres also a option for AMD processors.
These processors are best for gamers they come cheap compared to intel processors and give a qualtiy output. Mostly now machines come with 8gb ram which is quite sufficient for running games and multitasking.Always opt for an external Graphic card which will cost you but it is must nowadays.If not a high end try getting a low end Graphic card. Dont overlook the case as it is important. Try getting a case which ailows more airflow.Cd and DVDs are not so common as people use flash drives but still get a DVD writer.
