When buying a laptop consider the following key things. THREAD.

First thing you'd want to consider is your budget. You budget is what will determine what you are going for and the price you are looking at.

The next thing is PURPOSE for the the laptop. What you want to do with it is what will determine what you are going for. For example if you are doing online research, writing, you don't need anything complex what matter is screen size, keyboard layout and average performance.

If you want to binge watch movies with it nothing else? Then go for that with good quality screen -1080 to 4K resolution would serve if anything else doesn't matter. Tablets could also be nice for portablity reasons

For graphic designers, developers and computer programmers this is where confusion comes in. In many cases some buy that which will not satistfy their needs. If you are a video editor, you will need a larger storage capacity 2TB to 12TB and more depending, you will also need...

..a graphics card be it NVIDIA or AMD. Graphics cards are confusing but taking NVIDIA for example, you need to understand graphics card naming scheme to get the best. If you see GT 740M, 7 stands for generation, 40 stands for series. 740M therefore performs faster than 820M

You can find one like GTX 1050 TI

X50 means entry-level,
X60 mean mainstream,
X70 - high end,
X80 - Entusiasts
TI - Titan (To mean the Best of that pack)

GTX 1050 TI therefore means "Best Entry level GPU" alt GTX 1080 TI is the best you can go for tho' price is high

Many shops and sellers lie to customers, students that certain laptop will work best yet they have no clue, theirs is just to sell. Be careful

Another thing is the unending debate of choosing between Intel Core i5 and Intel Core i7. What I would advise is that look for generation of these two processors at the settings section. You will see something like Intel Core i5 -8200U first 8 means 8th generation (latest is 9).

8 gen this means it can outdo Intel Core i7-5005U (5th gen).. in some computing tasks.

After all these and budgetary considerations, search around for options within your budget you'd want to avoid rushy decisions. Don't buy that will be useless rather than saving for long IMO

If these things don't make sense to you or you are abit overwhelming then don't worry just ask someone or even DM

Otherwise retweet to help a friend.
