New PC - is a Gaming PC needed these days?

Thanks!

Just found that my old PC had a pretty well sized hard drive of 905 GB... I never upgraded, so I'm pretty surprised that it was this big on a cheap low-end computer, and this is probably why it lasted for all these years (and still does if I accept long loading times for ts4). I think I will need to go way beyond 500GB on my next, but don't find anything near that size on the affordable offers. Assuming that just the OS itself will take up way more space than my old Win 8.1. These days storing in the cloud might be more common, though.
