Well, I am a big Intel fan boy, so in a budget range you can pick up an i3 or i5 9th generation, I currently am running an i5-8600k still and a 1080ti and am getting some decent frames running in 1440p
Intel i5-9400F -

Intel i3-9400F -

These would pair with any Z390 mobo such as -

Also, these are decent ram sticks, Im currently running them myself for about 4 years now -

But an 8gb kit will still be good but 16gb helps future proof aswell, anything from 3000mhz to 3600mhz will be more than plenty
Now I don't know much about AMD but I know with the new 5000 series the 3000 series is a really good CPU to get at this time so that might be worth looking into if.
And with the new GPU releases, you won't get amazing performance out of the 1050ti but it will do for now, just don't expect anything amazing out of it. If you wait for some time for the 30XX to get steadier stock and the AMD RX series to gain more aswell, you can most likely pick up a 1080ti or even a RTX20 series on the cheap for a couple hundred.
You may need to upgrade the PSU if you go for a higher GPU however.
Sorry if this is a mess, I don't really use the forums that much and I am actually in work so I'm not meant to be browsing forums, it's queue update day for the 3090 so I cant keep away.
If you have a rough budget I can probably help more but that is essentially a very similar setup to what I'm running and mine cost me almost double what you would have to pay now. You can definitely run the latest games in 1080p with this if you upgrade the GPU, as I said I game in 1440p and I have a 144hz refresh rate and I maintain steadily above it.
Also maybe grab a 240gb SSD for faster boots if it does not have one already.
