Does Pegasystem CRM really new 30 CPU’s

We are looking at Pegasystems for our CRM solution – they stated that to run a large site we need 30 CPU’s – 40 Gig of memory and 200 gig of Harddrive space.

1) Has anyone installed Pegasystems – does it really need that kind of horse power.

2) Is it a dog on less CPU’s?

I know they only have 120 customers – but is anyone out there using it???

Thanks
