         | 
         | I don't know what the grey market premium is on the 4750G these
         | days though. I got my two 4650G processors last November, and
         | it was only about $20 over suspected MSRP to get them on
         | Aliexpress, but 4750G at that point had fewer vendors and a lot
         | bigger premium. At that time, US based marketplaces bumped the
         | price by another $50+, so I took my chances with Aliexpress (I
         | had to order my chosen SFF heatsinks there anyway, so I had a

         | fine.

       | 48Hz seems a bit too low. I think high refresh rates improve the
