Quote Hello everyone, my uncle likes to use powerdirector 19 ultra. He would like to work in 4K soon.

For this he would like to buy a new PC after many years.

It's planned:

32GB G.Skill Aegis DDR4-3200
PureBase 500DX
be quiet! Dark Rock 4 Tower Kühler
Ryzen 7 5800X
MSI MPG B550 Gaming Plus
500GB Samsung SSD 980 ( for System)
1000GB Corsair Force Series MP600 Pro (for Project)
550 Watt be quiet! Straight Power 11

Which GPU would you recommend?
The codec he uses is H.265 / HEVC

Thanks Alex

Alex,

1. Instead of an SSD for project files, I would strongly recommend spending the same amount of money on a bigger HDD. The read/write speeds encountered in editing the videos encoded in HEVC will be well under the capacity of a modern 7200rpm HDD. SSD is just a waste of money here.
2. As video cards, the latest harware encoders are the one found in nvidia gen 20xx and 30xx cards. Get a GTX 1650 Super if you can find one and will be sufficient. All of them have the same encoder, so don't try for the best "gaming" card.

3. The CPU will be used the most, generally not all effects or transistions are GPU capable, so they will use the CPU. Here I feel that 5800X can be a bit of a limiting factor and the extra oomph provided by more cores will be definitelly a good thing. 5950X for the win if you can suffer the price penalty!
4. Power supply needs to be at least 750W if not better. Don't skimp on that, it can take out the system!
5. Ryzen 7 likes the RAM to be at 3600. If that's not breaking the bank, it would be a good addition.
6. I would go with a X570 motherboard for those new CPU's.
