K501 Asus.

Laptop price after GST commencement is no longer so cheap. Asus VivoBook i5 is around 2.8k now. i3 one is 2.2k.
Maybe you can consider non-touch screen.

You will need professional colour calibration if you wanna take the post processing seriously. You will definitely need it. Can't stress it more here.

The screen that is not calibrated usually has more contrast than the one which has calibrated. Personally experience here. Calibrate for the sake of your photos!

If the price is a concern, I think the Envy13 will work good for your LR work. Should be good enough imho.
Spectre has a better quality build. But 128GB is really not gonna be sufficient for your photo storage. My 120GB SSD is a perfect example and I ended up getting an external hard disk for storage.

Have fun with your new laptop!

abang lately banyak busy dating ke?

Hi, hope my amateur comments can help a bit.

Set A
Yes, Guilds War 2 is kinda demanding. With your current budget, the best graphic card that you probably can get is GT930M which can run the game at low settings with 50+FPS IINM. Hence, not much choices. But feel free to check out the two laptops below. They are less than 2.2k and weigh around 2kg too.

Set B
Although Illustrator and PS deal with graphic work, the CPU is always more important in this case. Core M might not be very good for PS and Illustrator, the rendering time will be longer and not that smooth. However, the integrated graphics should suffice imho. The 515 can run D3 in high settings for about 30+ FPS, so no worries about that.

May I know what do you mean by a good screen? If you do not mind a TN screen that appears to be slightly bluish-tinted, i would suggest you to go for the Lenovo U41-70. 1.7kg with decent battery life (around 6 hours). The latest price I saw was 2.95k with 2 years warranty. Despite the bad aftersales service by Lenovo, this model is one of the best products by Lenovo imho. Should be good enough for all your game, graphic and Auto-CAD work. And it comes with full SSD performance too.

Hi! Hope my amateur suggestions will help a bit.

If I assume sRGB colour profile is the your accuracy measurements, you can either go with MSI PE60 or Dell Inspiron 7559. Both laptops basically fulfilled your requirement in the term of screen size, storage and the powerful processor. Both has the empty M.2 slot which allows you to upgrade it with SSD. But if you do not mind the lower battery life of the MSI PE60, do consider to get it over the Dell 7559. Although both models come with the FHD 15.6" screen, the MSI one offers a screen with a much better sRGB score (PE60=97%, 7559=90%).

All thanks to the examination and an extensive factory calibration process by MSI True Color Technology, the panel quality is very accurate. Not much panel scores more than 97% sRGB. And also, it comes with 6 True Color Profile that you can choose to suit your eyes in different scenarios, be it gaming, graphic work and etc.

PE60 is also cheaper than the 7559, and you can use the rest of the money to upgrade the RAM/SSD.

Happy hunting!

He recently very busy. Haha you can stop by kampar la. I bring you around also can

Notebook check

Acer V Nitro

SSD means solid state drive. The reading speed of this drive is so much faster than the typical HDD. The random reading speed can be faster up to 50X IIRC. Hence, your laptop can read files faster, hence the smooth.

Consider this. Then ask the dealer to change full 256GB SSD and 8GB RAM for you with your remaining budget. Then take out the previous HDD and get a external case for it to be used as external hard disk.

U got stock? How much?

Not recommended.

This price is already ridiculously good for GTX980M + SSD.

Are okay with DOS laptop? If you can install everything by yourself, get the 7559. I5 is sufficient for coding. There is no need for i7. And you can always upgrade the empty m.2 slot with ssd.
