In the long run, yes - but what myrice is doing will keep changing as we figure out how to do it best. So it is unimportant for you to do it now, and your time is in fact better spent on optimizing your slow hashes, etc. than on raw SHA-256 currently, now that you got it working to the same extent that other fast hashes on GPU do (at least passing test and reaching raw SHA-512's speed).
