Hi there, it seems you know the ports well. I was doing research for the past weeks, where i surprised to find Lenovo T490 offer TB3 just under 4000. More refer to this Lenovo T490

But fortunately, i digged deeper and found out this review by notebook check under "Gaming Performance" which it stated "The Thunderbolt 3 port that Lenovo has included only utilises two lanes of PCIe, which is not enough to get decent performance from an external GPU". More details: >> T490

So is the laptop i mentioned earlier worth buying ?

As per the title. Will you consider TB 3 is a must when you want to purchase a laptop now. I have a dilemma, whether to get TB3 or just get a laptop with DP 1.4 and HDMI 2.0. Spending extra RM 1000 make sense ? original budget is 3.5k-4k.

Refer to this if you interested in my previous discussion: https://forum.lowyat.net/index.php?showtopic=4869826

The 4k monitor is tempting. With that price. But I gonna use another 4k external monitor as the main one. Which meant I will off the laptop monitor and only use external 4k monitor. Will this still stress my stress my gpu?
