Whatever you choose, do not buy one with dual graphics (Nvidia + integrated Intel). It is almost guaranteed to cause crashes and other problems. Only one GPU! The reason is that Photoshop uses the GPU very actively for actual data processing. It goes back and forth - it's not a passive one-way flow like it was in the old days.
256 GB system drive is too small. That is not nearly enough for the Photoshop scratch disk. 500 GB should be considered minimum.
The published system requirements are just sufficient to get Photoshop installed and perhaps play with a few small images. For any serious work, you need much more.
