Hi, Need suggestions and opinions from all the experts here.

1. Preferred brand : Asus, (can consider other brands if no available options)
2. Budget : around RM2.5k - 2.8k
3. Usage : For uni work (a computer sc student, doing lots of programming and coding), gaming (overwatch and dota2) , stream spotify, browsing
4. Screen Size : 15" Preferably FHD (prefer anti-glare, due to long hours)
5. HDD : 1TB, ( something which is possible to be easily upgraded to ssd)
6. RAM : 4gb (must have availability to be able to upgrade) or 8gb

Thanks in advance

I am considering either one of these 2 laptops.

Lenovo Legion Y520-50MJ
RM2,980
i5-7300HQ
4GB DDR4
1TB
NV GTX1050 2GB
15.6"FHD
W10
2 YRS ONSITE + 1 YR ACC DMG
45 WATT BATTERY
2.4 KG

Or

Dell Inspiron 7566-30414G-W10
RM3,030
i5-6300HQ
4GB DDR4
1TB
NV GTX960 4GB
15.6"FHD
W10
2 YRS PREMIUM
74 WATT BATTERY
2.62 KG

Im stuck in deciding between these 2.
The downside of the Lenovo is the small battery.. which is almost half the battery life of the Dell.
Im currently leaning towards the Dell because of it's longer battery life.
But, I've also heard some feedbacks from others that it is much better to get the GTX 10-series compared to the 9-Series..

Is the GTX 1050 and the 7th gen processor that much of a jump in terms of performance for my usage?
My Usage : Mainly Programming and Coding (CS Student), MS Office, Browsing and Gaming (Overwatch, Dota2, CSGO)

I need help from help from all the experts here to make the best possible purchase. Appreciate all your feedbacks and opinions.

In terms of after sales service, which brand is better in Malaysia? Lenovo or Dell?

1. Preferred brand: any
2. Budget: 3.2k max
3. Usage: Photoshop, video editing, programming, normal gaming like dota2 and overwatch
4. Screen size: 15"
5.RAM :8gb
6.Preferred - Not too heavy, FHD

Which should i get?
Asus A556u or Acer E15-575g

Both laptops has the same specs and price.

i5-7200u
4gb ram (up to 16gb)
GTX 940mx
15.6" FHD
1 TB HD

In terms of design, I think Asus looks more modern.
What do you guys think?

Anyone here used Asus Vivobook S15 before?
Equipped with 940mx

Should I be buying a laptop now? Or should I wait till 8th gen is widely released? Is it a huge performance bump from then7th gen?
