All the PC parts should be compatible on paper but if there is something standing out please let me know. Or if there is a better alternative that I am not aware of, I would love to hear your thoughts. Thanks!
PS. The 6750xt was $379 just yesterday :( Missed my window.
It is an SSD but its using SATA as the interconnect so its limited to Sata 3.0 speeds which caps out around 600MB/s. So while it is an SSD not all SSDs are the same. So typically the 2.5 inch ones are a bit slower (in theory).
