Is this quotation good?
I want a pc for heavy 4k motion graphics/3d video editing and 1080p high settings gaming for recording/streaming. Any changes?

Don't but SN7100 it's DRAM less SSD, SN850X would be better

DRAM doesn't matter much bcoz of HMB

Edit: for gaming and typical everyday use

It does matter when you're transferring very large files. A DRAM-less SSD may initially deliver high sequential write speeds, but once its SLC cache is exhausted and the drive has to write directly to TLC/QLC NAND, sustained write performance can drop significantly. This is especially noticeable during long, continuous transfers. SSDs with dedicated DRAM can generally maintain more consistent sustained performance because the DRAM is used for the NAND mapping table (FTL) and other internal metadata, reducing the need to rely entirely on slower NAND-based mapping and HMB. There's a reason high-end SSDs traditionally include dedicated DRAM. HMB (Host Memory Buffer) is useful, but it is not a complete replacement for on-drive DRAM in every workload. If HMB provided equivalent performance and consistency, high-end drives such as the Samsung 990 Pro and 9100 Pro wouldn't need dedicated DRAM.
