Hi guys. Which one more worth it? I'll be using it mainly for work and light gaming/movie if time permits.
Edit: light gaming means city skylines

I dont think i need the 144Hz, 300nits display but i7 > i5 right?
Can an i5, 16GB ram, 256gb ssd beat an i7, 8GB ram, 128gb ssd?
Which configuration can last me many yrs without need to upgrade?
Please advise.

I want at least 15" display and keyboard with numpad, min i5 and 8gb ram. And originally budget around rm3500±.
Was looking at Dell for after sales service but only their gaming range have what I want.
Since I end up at gaming laptop range, legion seems the least stand out in terms of design. (I hate the eye catching gaming laptop designs and also it is not presentable/appropriate)

Of the 2 options, which is more worth it?
Other than T480 any other suggestions?

Battery life is not important. I will be plugged in 100% of the time.
I have compared the same config from Lenovo site, price is higher even after 15% discount. Out of the 2, the i7 one seems like I save a lot.

Just wondering how does the i5, 16gb ram, 256ssd go up against the i7, 8gb ram, 128ssd?
