Also, remember there is a benchmark to do a check on your computer and how it runs ffxiv arr. Im on my phone at the moment, so itd kinda rough for me to check the link to download the benchmark, but try searching for it via final fantasy xiv benchmark. But with the specs you describe the pc seems to be on the low end sadly. Like Eye said, it may run but it most probably do a lot of strain on the pc in general.
