rtx 2060 would work just fine

Really? I would say GPU first as I dought GPUs are going to get much better in the coming months (yah theres navi, but that's not coming until a lot later and we don't have any info whether its going to live up to the hype) but Zen 2 is almost certain to come in a few months and be a huge upgrade over current gen stuff. Also you will get much more FPS out of a better graphics card than a better CPU for now.

Look for an email from where you want to block. Click into it and then click on the 3 dots on the right and select Block "____". If you receieve spam, click on the 3 dots on the right again, and select Report spam, and gmail will do a better job of blocking that kind of spam

You'd have to check which one is being stressed harder when in game to know 100% but I'm almost sure that will come back to the i3 slowing it down a whole lot more than the 1050Ti. I'd personally upgrade the CPU first.

The 1050ti is still very good, obviously not the best, but still good.
 
your i3 is only a dual core. Definitely upgrade the processor first. If you're going to hit a bottleneck, it'll be your processor 99% of the time. 
 
You'll need to get a new motherboard to do it but I think it's worth it. I'd even upgrade to 16GB of RAM before considering upgrading the GPU.
 
You will still benefit from the higher refresh rate monitor even if you don't actually feed a frame for every refresh cycle. 

If 144 FPS with Apex Legends is your goal, see how close you can get to reaching it. If you still can't reach it even if you set everything to low, then upgrade the CPU first.
