hard time thinking "systems"

[Ordinarily_Greater]

hey there guys, I am having hard time choosing PCs. Before i talk about the PC, i will give 5 points as reference to what condition i am in

1. Budget and Location

i would say the $1000 USD level, but since i can't go for PCPP because I am in Indonesia. Also the taxes here also the mining thingy makes 1070 as expensive as 1080 in retail stores....

 

2. Aim

I will do JavaScript things (not a problem), using premiere pro while opening chrome tabs, and occasionally game at high refresh rate 1440p (for now it is just an ordinary 1080p TV). The heaviest i will probably play is PUBG

 

3. Display

As mentioned in the AIM section, 1440p/75hz>. i want my rig to be ready for that resolution

 

4. Peripherals

Logitech G633 Artemis Spectrum for $112, and Logitech G502 /w/ G410

 

5. Why am I Upgrading?

This goes the long discussion. so i currently have a poor man's PC, which apparently contains:

Core 2 Duo

Pixelview GF9400GT (Graphics Card)

1GB DDR3 (RAM)

Asus P5G41T-M LX

mATX OEM Case

300W OG PSU

 

I was wondering if i can actually save some bucks by just upgrading my old system with LGA 771 Xeon and a 480 8GB. But will it be sufficient than getting a newer system like these lists?

Also is waiting for Zen+ and apparently get X370 board be the perfect way either? I mean it will be better at scrubbing timeline compared with upgrading my CPU's old system to a Xeon X5450.

so yeah here are some complete PCs i found:

-Ryzen 5 1600
-asus prime a320m
