We run a 3.8.2 instance that big on a virtual machine running on an  
ESX server.  The VM only has 2 GB of RAM, which is sort of OK, but  
could do with being larger.  If I were to do it again I'd use a 64-bit  
OS rather than 32-bit, and give it more memory (probably around 4GB).

Nevertheless, our 2GB VM with two virtual CPUs handles our RT  
requirements quite happily (roughly 700 tickets a week, so not quite  
as high as you're envisaging, but not far off)
