Wondering whether it's worth the upgrade to 8gb ram and end up not needing the extra ram.

8gb is almost the minimum now to run windows. If 8 to 16 it might be something to think. But 4 to 8, it's a no brainer. Just go for it.

4gb enuf de. but processing/exporting is slow abit.

my curent laptop is asus k501l.

8gb just ok. as long as better cpu/gpu/ssd

for better performance, i use my desktop.

4GB can run, but when compare to 8GB, u can feel the big diff
But 8GB to 16GB, not feel so big diff
Anyway, Im using 16GB, because sometime need to launch PS from LR, or use other software/browsing

Is the difference between 4gb and 8gb huge?

P/s Acer S13 with 8gb ram RM3399 or Lenovo 710s RM3299?

Acer s13 8gb RAM RM3399 or Lenovo 710s 4gb ram RM3299?

well it's enough to run lightroom but it's little slow compared with 8gb when rendering
for fast rendering you should focus on processor
that's where you can see a huge different in term of how fast its rendering

Which laptop would you recommend: Acer S13 8gb ram RM3399 or Lenovo 710s 4gb ram RM3299?

i would go with s13 since it comes with 8gb and 256gb ssd compared with 710s that only comes with 4gb and 120gb ssd

Nowadays, new laptops and desktops are equipped with 8GBs of RAM. Simply because that amount looks like the minimum requirements to run Windows 8 or above. Hence, if you are going to use Lightroom frequently, 8GB would be fine. Personally, I would place a buffer zone by adding additional 16GB (which I did) to ensure overall optimisation

Lightroom performance basically depend on 3 things
1. HD/SSD - the loading speed (not processing performance)
2. CPU - the speed of process/render the photo
3. RAM - the work space for photo editing

How about GPU?
Answer is almost NO, and NO on export photo. If using LR6, it only affect on when from view one photo to another photo(the rendering time that actually very shot)

If you comparing notebook, if same generation CPU, CPU performance not much big diff, so, you can ignore CPU

Usually we use SSD as main disc to load OS and application, photo put at 2nd HD (bigger space)
Mean, if u want window or application load faster, then main disc SSD, 2nd Disc normal HD
NOTE: SSD will not help on processing speed
If your notebook only can take 1 HD, then you have to choose SSD or HD

RAM, this one, better increase to the number that you can afford
If you can afford 8GB, get it

4GB and 8GB RAM, big different, so, at-least get 8GB
Remember, your OS also need some RAM

Last, if you focus on photo editing, the notebook screen is very important, suggest you bring some photo to show room test
Open the photo at the notebook and check the dynamic range, some low cost screen not able to show some detail of the photo
e.g. The dark area, it show full with black, but actually there is something in the dark area

Glossy screen will make you difficult to edit photo at some place (because of the reflection of the screen)

Lastly, after buy the notebook, send it for someone to calibrate the screen for color accuracy

Where to send for colour calibration?

I have to say sorry that, I do not know...
Although I got my notebook from Illegear (which they got calibration service)
But due to I have a desktop and a notebook, I end up buy the calibrator my self and calibrate my notebook and desktop
So that they able to show same color on different screen.

If you really serious about color, you may check at lowyat forum, they may have someone provide such service
Else, you take an Ipad, open a photo, at your notebook, open the same photo, then at your notebook, tune your notebook color same as Ipad will do
Use Ipad as reference, because Ipad's color many people can accept it.
