As you see there are lots of dropped frames at 1440p but none at 1080p. I figured my high-end rig could handle it but maybe not?

PC specs:

CPU: i7-7700k @ 4.8GHz
Mobo: ASUS Prime Z270-A
RAM: 2x8GB DDR4 @ 3000MHz
GPU: GTX 1080 superclocked
SSD: 275GB Crucial MX300, ~50% free space

I've been able to do 1080p 60FPS just fine all along, the video turns out nice and smooth (using simple mode, indistinguishable quality, mp4, x264 encoding). But I got my 1440p 144Hz monitor yesterday, and just tried to record with the scaling set to the same (2560x1440), and the video turns out choppy, even though everything is silky smooth at my usual 144fps while playing during the recording.

Is there anything I could look at changing, or is it just that it's too much for even this cpu to handle?

I should also say, I tried it with NVENC and it's smooth, but comes out to about 1GB per minute, way too big.

Encoding 1440p at 60fps and also playing a game is a bit too much for that I7.
Your only option would be NVENC or Quicksync.

I see, I'll just stick to downscaling to 1080p then. Out of curiosity, would the Ryzen 7 be able to handle it, or do the extra cores not matter much for it? I was debating between 7700k and Ryzen 7, went with the "safer" option.

Use the NVENC encoder and you should be able to record at 1440p. (I'd recommend these settings) The quality should be the same.

Yes I know, but as I said NVENC makes it 1GB/minute which is crazy big

Sorry must've missed that. You can try using VBR set to around 60,000-80,000. (Should be about 0.5 GB/min) The quality will be lower but still pretty good (about equivalent to shadowplay). But if size is an issue for you 1440p isn't the best option.
