2k resolution

Hi, This is my system: Ryzen 3 3200G ASUS A320M-K 16GB RAM 256GB SSD 1TB HDD My current monitor is LG E1940 (720p). I'm planning to buy a monitor with a good colour gamut and good factory calibration. I've chosen the BenQ PD2500Q (1440p).😋 My doubt: Will my CPU be able to handle this...

So I tried making a custom resolution in the Nvidia control panel on my Viewsonic XG2405 at 2560x1440 and at first I thought it failed but then I checked my resolutions in my display settings and somehow it was there and to my amazement, it worked and mind you I am running this using HDMI cable...

What's up everyone, since I was supposed to ask about all the components, I decided to put them all in one thread. My budget is from 450-550$. Want some suggestions for s good pc build overall.
