To OP; anecdotal evidence only -- and I certainly wouldn't recommend
using PPTP for a secure VPN solution :)  At my previous job we ran
PoPToP (PPTP) on CentOS and the older HP DL140 G1 1U servers and were
handling up to 1000 clients pretty comfortably per machine.  This was
with 1GB of RAM per server and a single 2.4GHz Xeon processor.

Left before we could migrate to OpenVPN which I think would have
slightly higher processing requirements. :)
