Budget video editing build

[famas]

Hey all, it's been around 7 years since I last built a pc and I've been totally out of the loop since then.
It's an old Ryzen 5 1600, GTX 1080, 16gb ram.

I don't game much these days but recently have been trying a bit of video editing in the free version of Resolve, only trouble is my pc is seriously struggling to cope (think it's developed a memory issue which also isn't helping)

I'm due an upgrade, but as I'm only doing this for fun, I don't want to spend a lot, though If I get into it more I may get the full version of resolve or premiere pro.
Budget around £700-800 for a full system minus monitor and windows, micro atx, atx format.

I need to start doing research, but is it possible to get a system geared towards video editing at this price point with some 1080p gaming on the side (no AAA titles), and how much of an improvement will it be over my current system?


If so can anyone help with an initial spec.

Thanks.

Resolve uses the GPU but limited to just one GPU in the free version

With this in mind, how would my 1080 compare to a newer card?
As a bench mark, what current card is comparable (if any) and what card is significantly better ( within budget)

I would prefer a new build, as I'll pass this one on to my daughter, but a side grade maybe an option for the time being if my budget is limiting things.
Like I say, I think the current memory has developed a problem and as it's all in an itx case, CPU cooler size maybe an issue.

If I was going for a new build I'd go with an ATX format.

Cheers
