Is it virtualization is good or stand alone server hardware is good?
Virtualisation's fine, stand alone hardware's fine, depending on what you're doing
Is it 8 core/CPU is enough?
No way to answer that, to identify the CPU required would require careful benchmarking of the current server, an extrapolation of growth patterns and a decision based on that data.
