LOL, so there is no Best computer for Poser 5. It's like using an 18 wheeler to tow a trailer with its butt dragging on the ground. It may go faster but it's not solving the real problem. What we need is a rewrite that makes the most of the modern chips, running the modern OS's.
Maybe Daz is right in developing Studio, maybe we do need good old fashion competition to get this trailer a new set of wheels.
At least we all have "feature" parity.

Three things endure Faith, Hope and Charity.
