The thing we are trying to avoid with hardware questions is "questions" which typically turn into long-winded discussions and don't end up with any real answer. The close reason at What should our custom off-topic close reasons be? elaborates a little bit:
This questions appears to be off-topic because it is about the operating system, hardware, performance, or compatibility. These questions are considered off-topic because there is often no definitive answer, so they tend to require too much discussion to be suitable for Q&A format. Try asking on BlenderArtists for support instead.
I'd say it's okay for questions to pertain to hardware; our "hardware = off topic" policy originated more from a desire to have a more concrete definition for a class of questions which typically fell under either "too broad" or "opinion based" (e.g. most hardware recommendation questions) or "too localized" (e.g. extremely specific hardware problems). Somewhere in there there is a middle ground, and those questions do get asked and answered from time to time.
Since we've graduated and we don't have to care quite as much about closing everything that we can't answer right away, I'd say we don't need a hard and fast rule to close everything hardware or compatibility related as a matter of course anymore. Using "too broad"/"too localized", while more general and fuzzy, serves effectively the same purpose.
As for this question in particular, I'd guess it's in "too broad"/"opinion based" territory, but it's really unclear, so I took the liberty of closing it as such.
