Lenovo Yoga c940 - Is there hope?

Hey all - I'm new to Resolve, and had been playing around with it on my older computer and decided to upgrade with the hope of doing more video editing on it. I'm primarily interested in editing HD, pretty basic editing but color grading and minimal transitions and effects at this point. The option to do some 4k would be nice as well, since all of my equipment will shoot in 4k as well.

I bought a Lenovo c940 15.4" laptop with the hope that this would be good for basic editing, but I'm having some serious issues even getting smooth playback of clips in resolve when trying to trim them.

Specs are as follows:
Processor
9th Generation Intel® Core™ i7-9750H Processor (2.60 GHz, up to 4.50 GHz with Turbo Boost, 6 Cores, 12 Threads, 12 MB Cache)

Operating System
Windows 10 Home 64

Display Type
15.6" UHD (3840 x 2160) IPS, glossy, touchscreen, 500 nits

Memory
16 GB DDR4 2666MHz (Soldered)

Hard Drive
1 TB PCIe SSD

Graphics
NVIDIA® GeForce® GTX 1650 4GB

I am currently using the free version of Resolve. When editing even HD video, I'm not getting smooth enough playback of the clips that i've imported to even do any meaningful editing on them. They are very jumpy, and even when I'm seeing that it's processing at 24fps, it isn't displaying them properly.

I feel like my older laptop without a discrete graphics card and a 5th gen i5 chip seems to do better than this one. I'm currently just editing some gopro footage, 24fps, HD.

My questions are as follows:
Do I have something wrong with the setup that is bogging down the system so much?
Is this system never going to be able to really edit video (even though it seems like it should meet the minimum specs, and I'm not even doing anything all that complex at this point)?
If I pulled the trigger on resolve studio, should I see a massive difference in performance since I'll be able to engage the graphics card more?

At the end of the day, if this is a bit of a hopeless endeavor, should I just return this system and look for something else that would work better (and what would that be for less than $2000 if possible)? I'm trying to stick with a laptop form factor as I do primarily photo editing on the road, but want to start mixing in video as well.

Thanks,
Nathan

Since this is a PC and your footage is GOP footage, you'll need the Studio version to get better playback. Or you can transcode the footage to DNxHR or Cineform, which should run smoothly in HD. 4K would be no joy on that machine.
