Does it really diffence between ram ddr3 and ddr4?

Y bro?give me reason

acer and asus are banned due to poor tech support. if it works well then is fine.

Brother or sister, RAM has already pass the age where faster isnt gonna get you better gaming performances. DDR3 and DDR4 differs in clockrate which you are not going to see much difference when you game.

I see that you did your research which i will give kudos to you.

Using the Acer to play high settings will pretty much depends on what game. Older game sure, newer games maybe because 950M is an entry level card (for me) while 960M is entry level gaming card (if it makes sense.  )

Bottomline is this

Better spec is Dell with one of the best after sale services and good cooling and best self maintenance laptop in the market.

This is my view the Acer i presume the newer model doesnt seem to be able to handle the heat very well because it is damn thin (it might throttle the speed thus negatively affect gaming experience) and its after sale services is bad compared to Dell.

If you have time, type in the model of the laptop and add in notebookcheck and see for yourself. Example dell 7559 notebookcheck and nitro notebookcheck to see.

Acer v nitro
Intel Core i5-6200U Dual-core 2.30 GHz

Agreed on that part, and to further reinforce the point Dell has been pretty nice with self repaired machines (there are even manuals supplied by them on how to service your machine).

As long as you don't try to mess up your laptop when servicing... 

People like me like to mess around so.......         

It's also worth mentioning that the Acer has a dual core, quad threaded chip (similar to desktop i3s), whereas the Dell has a quad core, quad threaded chip (similar to desktop i5s). 

Not to mention that the 6200U in the Acer is a low voltage chip which trades off performance for longer battery life, unlike the Dell which has a standard, performance-oriented chip. 

The CPU difference alone are already worth it. 

I just don't know why would people really want to go for manufacturer tech support - I'd rather had my laptop fixed by a third party (who knows laptops inside and out) rather than a manufacturer... 

Haha Wow. I think i would buy dell. But need to find for a DOS version. Cheaper

e.g. during warranty period.
and you bought 3 year extended warranty

If you know how to install windows or linus by yourself then it is fine if not best is to get with windows. Go to retail shops to find freedos. Happy hunting 

I prefer to buy dell because service is good. Specification which you have chosen is middle range with decent gaming and decent overall performance.

Agree with Dell, I got myself a 7559 too. That extra RM400 on better non-upgradable CPU and GPU is very much worth the money.
