Advice on Upgrades

[JustinHunter]

Built my first gaming PC about 7 months ago, and have been loving it ever since. I recently upgraded my monitor to 144Hz 1080p and now I'm looking to upgrade other part(s) in my system. The maximum amount I'm willing to spend is going to be around $300 - $400 CAD. I was looking into getting the Sapphire Pulse 5600 XT but at the same time I was thinking of waiting for AMD's new lineup of GPU's dropping at the end of this year (hopefully) in which I could possibly pickup the 5600/5700 XT for cheaper. Any advice on any other component in my build is welcome as well. Here's my build: 

 

CPU: AMD Ryzen 5 2600 3.4 GHz 6-Core Processor  
Motherboard: MSI B450 Gaming Plus ATX AM4 Motherboard  
Memory: Team Vulcan 16 GB (2 x 8 GB) DDR4-3000 Memory  
Storage: Samsung 860 Evo 500 GB 2.5" Solid State Drive 
Video Card: Gigabyte Radeon RX 570 4 GB Gaming 4G Video Card 
Case: Phanteks P300 ATX Mid Tower Case  
Power Supply: Corsair Vengeance 750 W 80+ Silver Certified Semi-modular ATX Power Supply

If your not satisfied with the performance of your rig upgrade now 

Because waiting for new components won't do you good because then you will want to wait for the next next gen and you won't end up upgrading anything 

But if you are satisfied with the performance and the system does the job for you then wait
